2008 75K Auto TRANSMISSION ISSUE::
When I shift from park to reverse, the car jerks significantly. This ONLY happens when the car is "COLD". Few days ago I accidentally shifted to “L” while going 20mph and am wondering if this has anything to do with it. Bought car at 40k and have not changed trans fluid since. I dont think its the motor mounts because it only jerks when shifting cold at start up. Someone told me it may be the pressure in the solenoids?!?
ANY professional advice is Greatly appreciated! TIA

 

why don't you try changing the fluid

 

Do you park on an incline? Start by checking the fluid level. Then fluid change as thoiboi said and finally pressure switches if nothing else works. If you search for each of those topics you will find more knowledge than any mere mortal could wish for. Good luck.

 

I have 2008 with 93k miles, and it does the same thing when it's around 10F or below.

ATF was changed 3x3 when I bought it with 72k miles, and changed again around 10k ago. I also did pressure switches, and as it helped with shifting between gears, there is still delay before engaging reverse/drive from neutral/park and that jerking when really cold.

Change fluid anyways, but my guess is that this car just works this way. If I don't park on incline (if car won't roll if in neutral, with brakes off), I usually apply brake only enough to let shifter lock off. When I put car in gear, it moves the hole car and jerking is not that bad.

 

change the fluid, perform the 3x3 and you will see differences in shifting.

 

 

why would you waste time and energy at that place?

 

 

 

lol all the waffle I saw is either over price compare to new one or that scuff to hell.

 

 

I did it to check if there will be any difference, and I'm pretty sure there is. But there is no way to really measure it

 

Not sure what the temperature is where your at but when the car is cold and stays outside and temps are cold don't forget the lower engine torque mounts are hydraulic filled and if the fluid is cold the mount will be somewhat stiffer then when engine reaches normal temp so this may be what your feeling.

 

I have a 2008 base TL and does none of that when I shift. I just hit 30,000 miles. Changed my transmission fluid @ 10,000 miles in 2012 with the redline protocol that is the subject of that large thread. Redline D4/LW racing/F. Original pressure switches. no worries.

 

Same thing on my 07 base, the colder the weather, the harder the jerk when shifting from Park to drive, or Park to Reverse, or Drive to Reverse etc. However, once cars temperature is up, its significantly less. Its been discussed before, but that delay is part of the design of these vehicles. Im waiting to swap out my pressure switches, I wonder if itll make any difference on the startup shifts

 

I drive a 99tl and it does the same thing. It's been doing that for past 100k miles. In the morning I shift the knob to drive but the trick is to not let the car engage in drive. Try to shift it to drive and then shift it to reverse. See if that helps.
