........by saying I'd been trolling around in old motors for years without any issues.

Consequently, 3 days later, the transmission fell right out of the Corvette :D

Had a hectic day ahead of me finishing and finalising the group dissertation so I thought I'd drive in and save time, also giving me the chance to blat around chasing bits up and go to the binders.

I burbled along around the ringroad, listening to the smallblock gargle away as I shunted around amidst the Euroboxes slogging it out, finally reaching my destination. I turned into my friend's road, squeezed the throttle, rewarding myself with a sharp blat from the rear pipes............

.........Then I realised I was still just coasting forwards! :o

Blipped the throttle again and checked the gears, thinking I'd just dropped it into neutral without realising but nooo, no go!

Fortunately I managed to park, very neatly, about 20 feet from my friend's door so left the car there for the day whilst I worked. When I came back I checked the fluid levels (all good and not overly burnt or discoloured, do need changing but only 'standard service' fair), topped it up a little but still no go.....

Still, I guess one major mechanical failure after countless miles and 10 cars isn't bad going :D

I got it recovered to a local specalist just in case it was something simple (and to get it off the road) and it's not the fluid, definitely an internal problem in the box - haven't quizzed them yet to see what the issue might be but will in the next few days.

As the mechanical so aptly put it "It's got **** all drive, mate" :D

It really was a very odd failure - no slipping, no mechanical noises, clunks or warning, just coasting down the hill, turned in and ........like being in neutral! No drive in any gears at all.

I figure on 3 options:

- Get it pulled and repaired by someone with good experience
- Have a go myself (which I'm kind of tempted to, putting in a few shiny bits on the way)
- Or fit a replacement box....

Anyone done similar before? Talked to friend about it a little who recommended having a go myself (using one of those walk-through DVDs) but just wondered if anyone else had any input, suggestions, comments or advice regarding the matter.

I'm kind of disincined to get it repaired by any 'specialist', I'd rather someone with a bit of prior experience, if I did go that way....Maybe Penn autos or similar ;)

Shift kit and higher stall anyone?

:D

I figure it might be the oil pump or torque convertor that's gone, although I'd have expected a bit of a bang from the TC if it did let go!

Fortunately TH700 bits are easily found and not overly difficult to work on, provided you have some common sense - so it's a kind of a non-issue, just have to get the bits, or pay someone to do it.

Slightly dampens powder at the end of your uni term, mind!

Doesn't put me off it in any way shape or form, mind - just something that needs to be fixed. As likely to happen on any car as the next, unfortunately!

No hotlinking
 
thats a shame - are 'vette trannies usually pretty reliable? i'd love one as my next car, would probably go for an auto as well.
 
Yea, they're usually bulletproof - especially the 87's onwards - but mine is a very high miler and there's no evidence of any work to the box (I bought it knowing this, as a mini-project) - but didn't quite expect it to give up without any prior warning and it did drive brilliantly before, well, stopping driving.

Partly what's confusing me a bit at the moment is the fact that it had very strong takeup on the bands, no slip, no grief, no mechanical noises and was behaving exactly the same as my low mileage one - can't help feeling something has just stopped, like the oil pump, which isn't a bad fix. Wasn't even loosing fluid or burning it either.

I'm no auto-box specialist though so can't really say for sure :)

Much like all cars, there's only so far you can go before work needs doing regardless of how well it's put together or how strong it is :) Just as likely to happen to any other car on the road, unfortunately.

sounds like it could be the oil pump. I replaced the autobox in the rangey with a special from ashcroft, really nice gearbox. It's not really a job you want to be doing again and that's one of the reasons I went for a known good source.
 
sorry to hear... but hell, i really do like that rear end of the corvettes :)

shes not too bad on the juice either iirc?
 
Nah, I average around 16-18 around town and about 26, sometimes higher, on a run.

The later ('91 onwards I think) LT1 is a much more fuel effiecient mill though, I was averaging about 25mpg doing mixed around town and motorway stuff in that one, with peaks just over 30! :o

I'm certainly going to get it fixed, well worth it and it'd be nice to have the 'box as a 'known' component then - that I could pound on without fear - just working out the best way to do it really :)
 
Damn shame mate, hope gets sorted with costing too mauch time/money :)

Love this car BTW, and as Penski pointed out the plate is particularly awesome :cool:
 
Love the number plate btw :D :D

"****OWL" plates are pretty common on imports of that age, there are a few MR2 superchargers with them, not as many as there are "OVU"s though.

I'd probably go with putting another gearbox in for now to keep mobile then rebuild the knackered one at your leisure as either a spare or to sell on and get some cash back.

Of course if you don't *need* a car then go for the rebuild option anyway. If it all goes **** up you've still got the other options to fall back on.
 
Scott at corvette kingdom did all the work on our vette, he's a top guy.

TBH i wouldnt do it myself, very complicated and not easy unless you have a hydraulic ramp.

You could always go mental like us and fit the tremec t56 out the dodge viper, extremely robust.

This trans is for Pro Street & Strip use. Smooth part throttle shifts, & firm *** shifts. Will handle about 650-675 horsepower with a 10" or smaller torque converter. This transmission is custom built to match your engine, torque converter, & your driving conditions. One year warranty.

Price: $1,860.00

:D
 
Well, so far I've had quotes ranging in the 900 quid range for complete removal, rebuild and refit - which is pretty damn good going really, be more than happy with that :)

Going to keep trolling about though and get some more recommendations, first, however :)
 
that's a good price, but make sure they are a reputable firm. So many 300zx owners have paid much more than that to have the box fail again not long after. I guess there isn't much expertise in the UK for AT's (they run a ZF unit fwiw).
 
Auto boxes ain't fun to take apart.
:(

Course they are, there's nothing like the thrill of seeing a dozen springs and plungers flying out and rolling into the crud underneath some old workbench :D

With manual gearboxes you can even fire little ball bearings into your face when you dismantle the synchro hubs...
