No forward gears
Hi everyone! I just got my first corvette and have been a corvette fan since the beginning of time! My vette is an 84 with only 117,000 miles on it! I have reverse but no forward gears! It has been sitting since 2004! My question is, is there any troubleshooting I can do before yanking the tranny. Linkage, flush etc.? Thank you for your answers in advance! Peace, Kev...

Personally, I'd drop the valve body and thoroughly clean it.

Maybe the OP was not aware of the reason in order to state it. There is a reason a vehicle would sit for 13 years. I stand by my original advise. He says it is his first Vette. I would assume he would like it to run and be as trouble free as possible. It is an 84, hence the poorest model of these transmissions. If it is original, at 117,000 miles it doesn't have much life left in it even if the valve body cleaning accomplishes something. If this procedure does nothing, not only have you wasted a bunch of time, you have wasted a complete fluid fill and filter.

I'll probably pull and rebuild the tranny just to be safe! Tkank you to all of you for responding! I knew you guys would know! Also can I switch to synthetic oil in the engine? The oil is super clean but the guy before me probably changed it. Thanks again you guys so much!!

I run synthetic in all my cars, motorcycles and lawn mower. Its sort of a religion with me. I like something like Rotella T synthetic in older, high mileage engines as those oils still have a higher zinc level, which has been eliminated due to its effect on the cat converter. Zinc in suspension offers a "last line of defense" against galling in older, high mileage applications. I've read that the Mobil 1 high mileage formulas cover this as well. If you want to really get more information than you can handle look at "bobistheoilguy". Its just a forum so its mostly crowd "group think" sort of stuff but I tend to go with real user, real world input rather than the manufacturer BS.
