Firstly. I'm new to this site, and am very impressed with it! I'm also a newish tbi owner. I dont know much about these cars, but I'm reading through the posts, and trying to learn! OK the problem i have, is the transmission (700r4 I guess), is slipping as i accelerate with a whining noise before changing up each gear. once rolling at highway speeds the noise seems to stop. I checked and replaced the fluid, although the old stuff diddnt look bad. I am hoping its not going to be too expensive, but i dont know if it is the transmission at fault, or maybe the torque converter, or something else? If i need to replace the tranny/converter, will any 700r4 work? or do i need a certain type? same for the converter? The car is a '92 firebird 5l (305) tbi by the way. Thanks in advance for any help you can give!

 

...still desperate for some help here... i need to fix this!

What kind of fluid did you use? it sounds like you put the wrong kind in.

 

problem was there before the fluid change... but it was dexron 2 which was the recommended type. pretty sure its not a fluid problem, but thanks for the input!

 

Sounds like the torque converter may be on its way out.

 

these trannies are cheap to replace
its hard to diagnose this problem accurately
i would suggest
1.transmission
2.performance converter
3. with a trans go kit
4. upgrade the input drum if you can
5.make sure the t.v. shortcommings are taken care of for a healthy 3rd and 4th gear

sorry i couldnt help more but im not there with your car either
if you hear a whine first thing after low fluid i would think of is a bad pump

 

Is it more of a lag between shifts and kind drops and jerks into gear? Test the TCC solenoid. Do a search. Theres a few different tests you can do. If you cant find anything let me know.
