Run fault codes and look for TCM problems . Have a pressure test done on the transmission to determine internal faults.

Overdrive comes in at about 42 mph unless you have
the gas pedal completely to the floor at a higher speed
& that is unlikely

Go to a trans shop,pick up their rebuilder or best guy or girl

1994 Buick Custom Regal 3.8L I changed ****** Filter and fresh fluid in it will go fine Thanks. But now at 60 mph rpm is 3,900.Maybe the overdrive is out? Any suggestion. Thanks.

Just having overdrive out would make it rev that high. It sounds like ur stuck in maybe 2nd gear. Did you add to much trans fluid possibly?

My 2000 Voyager has been jerking or jumping while driving. Sometimes it does it right after I turn it on & shift to drive. It just hestitates a little bit. Then we realized it does it occasionally...

Sounds like the transmission. Possibly the torque converter. If the car has automatic over drive, at 45 MPH is about when is activates.

CHeck engine light on?? If so take it to your mechanic or your auto parts superstore and have then read/scan the codes.

2009 Toyota Camry problems

All Toyota auto trans cars downshift when descending a hill when you tap the brake. This is called "Downhill Shift Logic"; what this is for is to eliminate the double shift when you come to the bottom of a hill and then accelerate. Normal condition. Usually happens above 38 MPH.
Also: The cruise will accelerate when going uphill. Normal condition.Plus: The cruise will not disengage back to the set MPH after you top the hill. Toyota recommends to disengage the cruise when encountering steep terrain.

1996 Corolla Auto Transmission problem

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.
