I have a 1998 Tiburon. It has 170k on the odometer. It shifts normally until it warms up, then the car feels like it's going into neutral instead of overdrive while giving it gas. I am currently driving it with the O/D off. Is there any thing that can be done besides replace the transmission?
Hi, Try changing the oil in the transmission and filter. Good luck.

Hi. 2005 Corolla CE. It's normal. They tend to do this when upshifting form 1st to 2nd gear. No timing chain readjustment needed.
96 Corolla. Overdrive not working properly, if not engaging after 45mph constantly. If driving on the city, is normal, but not after 45mph, when the car is trying to engage overdrive in order to save gas and preserve the trans gears. If not able to get help at the dealership, find another one and explain them the situation.

Most likely causes is the OD shift solenoid or less likely the VSS

I have that exact same truck and transmission and My Transmission did the exact same thing about a year ago and there was some kind of snap ring inside the transmission that broke. I originally thought it had to be an electirical problem because the truck shifted fine until OD or if i turned OD off. The 4r70w is a light transmission and i would suggest you have a shift kit put in and they make a heavier kit to beef it up.. Sorry its probably not the new you were looking for.

you may be confusing the torque converter clutch engagement with o.d. this trans has a problem with the T.C.C. regulator valve wearing out the valve body bore. this will cause the converter clutch to engage only sometimes or not at all. this will set a P1870 code in the control module. when this code is stored in the controller, ( check engine light may or may not be on), it increases the pressure in the transmission causing the 1-2 shift to be harsh. ask a local tranny shop to scan the vehicle ( most will do this for free) if this is the problem they can either fix your valve body (sonnax parts) or replace it with an upgraded valve body. hope this helps

Well, first do the service. Pull the pan down and look for metal shavings. If there is metal shavings your in for a transmission. If not, you may have a problem with one of the transmissions shift solenoids located near the valve body.
P.S. The Duramax has the Allison 1000 transmission not the dodge cummins and they are one of the best trannys on the market.
