94 z28 transmission problem

[tds1213]

I have a 94 z28 with an automatic transmission that has been having a problem. It runs fine but the transmission doesn't seem to want to downshift unless you shift for it. It still upshifts just fine though. I have no idea what the problem could be. Any suggestions? Thanks.

Transmission are hard to diagnose and first thing to do is check the level and condition of the fluid. If those check out the best recommendation I can give is to find a trustworthy shop to diagnose the problem for you.

I was talking to a guy I know and he said it might be a vacuum leak some where. Is that a possibility and if so any suggestions on where to start looking?

You have a 4L60E "e" for electronic, vacuum should not be a factor.

Someone on another board said to check the detent cable. Could that be causing the problem?

[wrightz28]

There isn't one!

[FormulaLT1]

After you check your detent cable make sure your flux capacitor has plenty of platinum . I am sorry I am stupid

Looks like its going to the shop.

yes, it could be a number of things from a 'simple' mechanical issue to a sensor/pcm problem. Just get a few different estimates, don't go with just one!

good luck
