It seems like every time I fix one problem on my vette, 2 more come to take it's place! then the origional problem comes back.


I had the car for a full month before stuff started going downhill, and now It seems like EVERYTHING is broken, mistuned, uncalibrated, malfunctioning....

I just replaced the tranny with one that is supposedly really really badass, but now it sounds like it grinds the gears around corners when I lay into it! the whole car shudders and growls and it makes me wince.

what the heck is that sound? it's started doing it in straight acceleration now, and in reverse, but only in first and reverse at sudden throttle application.

Things are always darkest before the dawn and the trials and tribulations, while a PITA, once solved result in a dream ride!

You didn't give us much to go on!

Year, miles, type of tranny, what else is going wrong?

I agree with GREASE remark

I assume the tranny has fluid in it? What about the Diff?

Tell us more, we are here to help

Hang in there. First, contact the vendor of the Tranny. GET SATISFACTION MARINE! I dont know what year model you have or anything else, but...decide what you want the car for. If its street, build for street. Biggest, Baddest isnt always good application for street use. I have a close friend with over 125 K spent so far. His problem is that my car is within 15 MPH on the top end. It kills him. Remember...Semper Fi. Be faithful to the brand.

Well, lets put it htis way. I bought mine, and so far I put in a new motor (with new seals, plugs, wires, etc etc), new master cylinder, alternator, waterpump, fuel pump, and like 4 other major things that I'm forgetting. All this crap happened at different times, and no, I wasn't expecting any of it (least of all a new motor!)

I'm FAR, FAR from anything resembling rich, or even "well off" - I'm a broke-*** colelge student, but admittedly I do like to **** around with mechanical crap.

And god, do I love this car (once everything is buttoned up and it runs again). You'll love it even more, once you realize just how much work you've put into it, and that practically every bolt has been turned by YOU.

It still needs headlight bushings, tires, weatherstripping all around, paint on bumpers, shocks (all are blown), new seat covers, and like 10 other things, just to make it "decent" - and i can't wait to get to that stuff

It's liek a construction set when you're a kid. it's something to do I guess. Oh and yes, it's my daily driver now.

Don't feel bad. Welcome to the love/hate Corvette disease. I was about ready to sell mine about a week ago (again) due to a shop problem. Wasn't the car's fault! As it is, once I pull the cover off it and everythings right, there's nothing better. Most of the expenses are the can of worms I open myself. My car as a whole is pretty sound , I'm questioning its owner Hang in there!

I also agree with the "got grease?" comment.

Also kind of sounds like the limited slip differential being that it's loud in turns. Make sure your rear end is full of GM part # 105227 gear oil or a good SAE 80w-90 GL-90 gear oil.

the car info is - a '93 with an automatic and 148K on the clock. Tranny replaced less than 400 miles ago.

I went over my vette and made a list of all the stuff that was wrong with it....and now I think I would sell it, if I didn't love it so stinkin' much!!

Yes, the tranny has fluid, and had not been acting strangely other than really weak shifts, and it was supposed to be a "performance" build.

The noise sounds like grinding gears and feels like ultra-fast wheelhop. It used to do it only when hitting the gas in a slow left turn, but then it started doing it in right turns, and now it does it even going straight.

I have not touched the rearend, and it performed fine last time I checked.

have you checked the 'c' beam mounting bolts? (the ones on the tranny and the ones on the rear end) since the trans was replaced recently, maybe they forgot to torque or tighten them.

I do not want to throw a wet blanket on the "we all love our C-4" club (I do too), but there comes a time when a car is worn out. All emotional attachments aside, they are just machines. You might consider getting another one like it, they are not terribly expensive anymore, and use your current car as a donor for parts. And , of course the stripped out old one would make a nice "for race only", chassis. Just an alternative, please don't run me out of town in a barrel!

anyone got a barrel?



(just fix it.. it'll get better.. heck if people can rebuild cars from a junkyard there isnt anything you cant do especially if you put your mind to it!!! - Especially like resotring a vette).

One thing to keep in mind is vettes will always have value.. some people would give a nut just to own a c2 in ANY condition..

I would not recommend stripping a perfectly good C4.. the car is almost 15 yrs old.. you can expect it will need a few things.. and she'll love ya for it...

Heck, I've just about replaced everything in mine.. and its better than new at this point.. besides were all here to help you out if you get in a jamb.. there isnt anything on that car that can go wrong that someone here hasnt already fixed..

THAT's an automatic??? You might have mentioned that a day ago. I'd get it back to the installer, ASAP.

RACE ON!!!

I installed it myself and I know the install was good to go... I've done it about a half dozen times now

I DID buy a new converter, a stock replacement from the local parts store.

The sound/shudder seems to be comming from furter back than my feet, but not the rearend.

I checked the c-frame bolts and they are all good

no u-joints are binding


I hope it's not all wore out, seeing as I just bought it in october! In any event, I'd still kill for one just like it with a 6-speed

When I said "installer", I was speaking generically. In this case, "builder" would have been a better term.

Your description of a "shudder" sounds like a feeling one would experience from a slippage somewhere. The only other possible source of slippage is in the posi traction clutch pack. I can only imagine the problem being with the transmission. With that many R&Rs, I assume the TV cable is properly adjusted.

RACE ON!!!

The reason for me asking was because I had a brand new converter shutter. Although I don't know why it would just do it around corners. Does it do it going straight if you get in to it a little? Mine would do it when I would give it enough gas to kick it down a gear. Hope this helps.
