My car gets up to 48 mph and starts to hesitate a littlr with acceleration. The car sat for 3 weeks pending tranny rebuild. What could cause the hesitation? There are no codes. Fuel pump is new, so is alt, dist and crank sensor.
Do you

Both the transmission and engine can cause a hesitation you'll need to rule out one. It is easier for me to check the engine and rule it out first. If your able to duplicate the hesitation in park I would suspect the engine if does not I would suspect the transmission. If the hesitation only occurs when in 4th gear at 48mph it would send up a red flag that the issue is with the transmission.
Check the transmission fluid level that it is correct and not contaminated or aerated.
These transmissions have a computer just for the transmission and another computer for the engine. When the batter is disconnected or almost anything replaced on the transmission will have to go through a shift quality relearn. What that means is the transmission computer takes input from the driver and all the sensors and creates a data base to improve transmission shifting to make it more effective and comfortable.
Driving the car will give more time to improve the issue or allow the computers to detect if there is a issue with the engine or transmission.

Thanks well it is under warranty. It does seem to be the transmission because it does not heditate at idle in park, but the tranny does seem a little jerky. I just got the car back last friday

The tranny seems to be smoothing out after six days, but there is a slight hesitation still if I maintain 50 mph or while slightly accelerating at that speed. It seems to occur after the car has warmed up and been on the road 10 to 15 minutes in stop and go traffice. Here is the thing, before my old tranny broke a month ago, the car was starting to hesitate at 50 mph when accelerating. My brother and I checked for vac leaks and took care some minor hose issues. Is there any other feedback you could give on this? I still am going to bring it back to the tranny shop anyway.

Does this hesitation only happen at a certain speed or can you get a hesitation to happen if you rev the engine (in park) to a certain RPM range?
During the transmission repair did the torque converter get replaced?
Do you access to a scan tool that can access the transmission control module to check for any fault code stored?
Let me know

The torque converter was supposed to be part of the rebuild. I am bringing it back to the shop tommorow. There is a puddle of thin reddish brown fluid leaking near the pass side front tire. It looks like tranny fluid. I dud hear on sunday a burp when I put it into park, that was two days after the fix. I guess I will find out tommorow. Thank god for warranties!
