Ford Transmission :: Slips Occasionally When Shifting Under Light And Moderate Throttle
Jun 4, 2012
The C6 in my truck is acting odd.. its into drive by 17 to 21mph under light throttle and under moderate throttle it slips occasionally when shifting, the 460 had a fuel spurting motorcraft on it, had to swap that for an edelbrock 1406 to drive it. The kickdown is there but setup for another truck. I don't know if the c6 has a vacume modulator or if its all controlled through the kickdown rod.. it does need a fluid an filter change that's gonna happen this week.. this trans just has me leery with the soft shifts.. its in 2nd almost immediately after takeoff....

4 months ago we bought a 2010 SF V6 with 70,000kms - we immediately noticed this very harsh 2-3 transmission sift under light to moderate throttle. Mostly in parking lots or accelerating slowly. Took it to the dealer and the flashed the ECU - - - this made the issue a little better.
I was reading around the net - the problem seems to be associated with sticky solenoids. I decided to change the fluid < 4 drain and fills > to Maxlife and I added a product from a company called Lubegard, this completely eliminated any harsh shifting at any speed or throttle.
I dont know if it was the additive or the 90% new fluid - however if the solenoids are the cause - keeping them properly lubricated seems like a good idea.
I will also be installing a Magnefine inline transmission filter as well. I have used them in the past with great results.

I've had 2 Elantra 2012 models 1 a gls the second a limited. As far as transmission issues both Elantra's from a cold start after allowing RPM's to idle down before taking off they both have started shifting hard going from 1st to second gear 1st car was around 8-9 k miles now 2nd started at 3 k miles. Since owning 2 cars same make same year same transmission and many times to dealer 1st car ended with Transmission replaced 2nd has now started doing the same thing they reset adaptive and next day did it again its now back at dealer waiting for them to diagnose again.

Why does my C6 shift at 4000 RPM when the throttle is open? My motor produces peak torque at 5000 RPM, and peak HP at 6500 RPM.
I would like to have the lower gear until I exceed the peak torque at least.

I put a transgo shift kit in the transmission before putting it in the truck, it also has a small stall. At half throttle you can manually shift 1-2-3 with no issue at all. Under full throttle when you shift to second it won't go into second until you push the shifter into third. Then it'll go to second and spin the tires when it grabs second in dirt. This is all in 4lo, I was gonna switch to 2hi and try it but it's raining and I don't feel like crawling under it to change it. The truck is a mud toy so will spend 90% of its time in 4lo.
I don't have a vacuum line currently hooked to the transmission because I have the same shiftkit (transgo) in my 77 and no vacuum line on it either and it works fine.

I have a 2001 Hyundai Accent with 120,000 miles on it. Up until a few months ago, its been a great little car. The transmission started acting funny by shifting irregularly and then getting stuck in 3rd gear occasionally. I took it to the dealer and they told me that the tranny is shot. The estimate for the repair is $2000.00.
I just can't see putting that much money into this car. It needs Struts, Shocks and a timing belt. Basically what it needs is what its worth if it were running well.
How hard it is to replace the transmission in this car? I have the 1.6L DOHC with the Automatic transmission.

2011 Focus 2.0L L4 engine, manual transmission, 70K miles - when up-shifting gears, the throttle remains high, dropping v-e-r-y slowly instead of dropping rapidly when the throttle is released. It is the same when not moving, when the throttle is run up to steady RPM's, then the pedal is released, the RPM's drop slowly. This has started recently, at first I thought it was just 'operator error', and that our shifting skills were deteriorating with age (ours, not the car), but testing has proven the fault lies with the vehicle. I researched sticking throttle issues, and thought I had located the problem as a bad throttle body assembly. Changed it out with a new one, went thru the computer reset procedure,and the problem still exists. No error codes are showing, but the little yellow wrench light is lit on the dash (resets each startup. Vehicle drives fine otherwise, no loss of power, etc.

I have a 2003 Honda CR-V with 150,000 miles that, up til now, has been a dream car. Now, at moderate speeds (30ish) it occasionally starts vibrating like I'm driving on a very washboarded road. It immediately quits if I let up on the gas. I don't notice it at higher speeds (freeway driving) or when going very slowly. It seems to initially be brought on by hitting a bit of rough road. I think it feels like it is in the rear of the car and it seems more noticeable on the right (passenger side). We had new shocks put on the FRONT about 3-4 months ago and I think the problem coincided with that but my husband disagrees and says he noticed it before then. We took it to our usually wonderful and reliable shop and, as could be predicted, they could not get it to replicate the problem. We took it back again and they drained and replaced all the transmission fluid thinking that might be the problem. It still does it, although I think it does it a bit less. It also seems to me that the car, which never had a very smooth ride, is even stiffer and bumpier than before. What's going on? Could this be a drive train issue? Transmission? Should we have also done the rear shocks at the same time as the front?

I have a 2002 Honda Accord SE Sedan. 119K miles. The transmission slips sometimes especially when I start after stopping at a red light. My mechanic recommended not to change the transmission fluid as the transmission can go down and might need a new transmission. He also told me that 2002 Honda Accords are known for this issue.
So my question: Is my mechanic right? Or should I go ahead and flush the transmission fluid and replace it?

I have a 2002 Ford Escape 4x4Automatic with 97K on it. It has just started slipping in Drive. It will go in reverse just fine. If i put it into 2 or 1 it will take right off then I can move it into D but only with the OD off. If it is on the engine revs and you don't go anywhere. I have no lights flashing or bells going off. The fluid is clean and doesn't smell burned. Is my transmission toast? Is there a chance I can have it fixed cheaply or even do it myself?
Here are the symptoms once again.
Moves in Reverse.
Revs in D with OD on or off
Moves in 1 or 2 with OD on or off
When you get it moving you can put it into D with OD off and get 3rd gear. If OD is on It just revs.
When you come to a stop in D with the OD off and try to take off again it just revs. You have to use 1 or 2 to get moving again.
Will the car make it 300miles home so i can have it looked at?

I just picked up a 2000 v6 passat with an automatic trans. I am new to passats, esp with autos. The cars transmission is having problems shifting with the trans gets hot (25-30 min run time) and slips. What is the trans code for this car and is it FWD or AWD? It has 220k, and the engine runs great. It was sorta an impulse buy, I plan on flipping it so hopefully tis a good investment. Any common things I should be aware of so I can get it tip top shape to sell it?

When my Excursion sits for a while, the transmission slips a lot at first till it builds up pressure. Is this a problem? It seem fine other than this.

1994 Lightning E40d... I was on my way home from work and noticed my speedometer jumping from zero to around the speed I was going on the highway. Then as i got off the exit I noticed hard shifting. It was in neutral between shifts for a few seconds and then it would go into gear jolting the truck forward. The abs light was the only thing on at the time. I tried turning off over drive only to get higher revs which scared me away from the gas pedal. Since I can't afford to replace my transmission. It happened all the sudden over halfway home from a 35 mile drive. I'm assuming it's some kind of electrical issue. What's going on with my baby?

I have a 2008 Ford Lariat F150 with 53k miles. The transmission seems like it slips at times. Here's the scenario. When I take off from a standstill and going through the gears at a normal acceleration pace, say I momentarily lighten the acceleration pace then try to resume. At that point, the transmission seems to slip momentarily, then bumps back into the pull mode. It feels like there is slack in the drivetrain until it re-engages, or like the lockup torque converter momentarily releases until the computer has time to react to the accelerator positioner calling for more. One guy said the transmission is, at that point, between two gears... either trying to decide to downshift or to upshift, but you can feel the surge in rpm momentarily until it decides ... then bump and your off and running again. If I push the O/D button, it stops doing it. What I can do? Because the dealer can't seem to get it to act up when they test drive it. It does it fairly regularly on me though.

My 2005 4.2 L transmission slips in overdrive but I turn off overdrive and it stops slipping instantly. What could be the reason for this does this require an entire trans rebuild or is it an easy fix.

I have a 2004 XLT supercrew 4x4 with about 150,000 miles with the 5.4 motor. I noticed that when entering an interstate at around 50-55 mph it feels like the tranny slips. There is a jerk, jerk, jerk than it stops, it doesn't do it at any other speeds and only getting on interstates. Runs fine in town. No lights on the dash or codes, fluid level is normal and clean. I did have a caliper sticking but it was replaced and it's still doing the jerk, jerk, jerk. Could it be U joints?

'96 Explorer 4.0l V6 4X4... 214,000 miles. So, I'm having some transmission slippage and was wondering what can be done about it. You see the mileage and the only thing done to the trans was a drain and filter/fluid replacement at 120,000 miles.
Here's what's going on... When cold, in the morning, I put it in drive, trans engages, I move maybe 20 feet and it disengages. I wait up to 20-30 seconds and it engages and slips right back out. I wait, engages, move 50 feet and it disengages. You get the picture. After doing this 4-5 times it will engage and I can drive a 100 miles with no problem. Seems like it need to build up pressure or warm up before it will drive normally. I've checked the fluid and it is at the correct level. I guess my question is, would I be wasting time and money to replace the filter and fluid again or is it just warn out?
I've read when a trans starts slipping after it's warmed up means it needs a rebuild and mine is the opposite.

I have a 94 E350 with a 7.3 diesel. I took it to the Ford dealership to have a new fuel filter and oil change when I got it back the OD light was flashing and transmission shifting hard. They tell me they cannot find a problem could they have possibly knock a wire off of something to make this happen...

finding out what is wrong with my Taurus. I have searched all over the internet not finding any posts about a similar problem. When driving after I turn past a certain point only to the left not to the right. The car slips into neutral revving, then once Ive straitened out somewhere along the wheel turning radius it re-engages in gear and lurches forward. The car drives fine and shifts smoothly except this.
