Hi Guys,

I live in the UK and have just bought a '87 IROC 350 tpi - my first Chevy!

My question is about the o/d, driving the car on the highway at about 70 mph the o/d wasn't cutting in. I tried a few times to back off on the accelerator and that didn't work. To prove it wasn't working I shifted from 'O' to 'D' and there was no change in revs.

My first question is when (what speed) does the o/d come in?
(I'm running standard gears)?

If my o/d isn't working what do I start looking for to trace the problems?

If any of your replies use abbreviations or acronyms please tell me what they are!!

Regards
Nick

Classic problem with these trans, and I have had first hand experience the "top end" shifting (or lack of)

You'd have to rebuild or replace to take care of it, in my opinion.

I babied mine for 30,000 miles and it just blew today!!!

if i leave my car in od taking off from a stop the car will usually shift to 4th gear before i hit 60 mph...thats babying it...if its floored it doesn't go to od until 80+


if you were closer to where i live im going to be selling my stocker for dirt cheap in the next month or so
