Took the Vette down the road and it is slipping like crazy in third and fourth. Not a pretty sound with a supercharged stroker motor.
If it is not one flippin' thing it is another...
Rather than pulling it, doing a tear down and rebuild the plan is to just replace it. A built Stage II 700R4 from GM is under $1,300; for the price difference the smart choice is to replace it, have a nice warranty and be done with it. I have a ton of luck, all of it bad
I'm in WI, but what is the stage 2 hp? Mine was built for 750+hp and broke now built stronger. A local place here can make it real strong for like 1500. Maybe shop around your area. I'd do that before off the shelf.
Also; I thought you had a th350 or 400 in your car?
I actually consider a 400 if this one breaks. OD is nice, but with the 3.45 gear in it now would not be bad. 3.73+ would be fun with a 700r but I get no traction with highway gears as it is even at 60mph roll.

Good memory! The Th350 was a couple motors ago I changed back to the OD trans since I'm doing more highway driving.
The trans that went was a built PeteK 700R4, it didn't slowly go out, it just flat took a dump. As I understand it the stage two has upgraded bands, the next jump up would move to the different planetary gears -- but that is well over $2K. I could shop around, but I just want to get it done and back on the road.
My performance car is now the twin turbo HEMI Dodge, the Vette has become more of a show cruiser.

Thanks -- I love that this is a one of one build. There was a totaled SRT with almost no miles on it so we graphed that interior into the Dodge. There too many body mods to mention... I did as much as I could on the Vette, so this was the next project. It is scheduled to do a photoshoot for Mopar Muscle magazine.
I use to have a 1977 Volare 318 and shifter console on the floor. Been looking for another one those for 3 yrs now. Nice Aspen
Yours takes it to another level!

Hi
Get used to replacing the turbo700R4 transmissions, they cannot handle the power for long. Have gone through 5 heavy duty rebuilt ones...... keep an eye on the half shafts, i had twisted some now have steel ones.
Sorry to pirate a C4 post; As a GM fan I'm partial to SS496's and GTO's but there is no denying a clean Mopar is eye candy. While the GM's are pretty much same-ol-same-ol a clean Road Runner or a GTX Hemi gets my attention. One of those with a hot cam and a big exhaust rattle makes the hair stand up. What does that twin turbo sound like?

One word - nasty. The exhaust note is very unique with the magnaflow bullet mufflers and the almost straight shot exhaust pipe. There is only one 45 degree angle going out the side of the car. You can hear the ball bearing turbo whine at the exhaust time.

Spoke with the shop this AM -- you are correct at my power level the transmission supplier did not feel this trans would hold up. They recommended the stage III 700R4.
This thread just makes me more depressed my car is auto. I hope someone buys it so I can buy a ZF6 car. But if not whatever. Say if I were to cam it(a small cam), ported heads, ported intake and LT headers, will I constantly be rebuilding 700r4s? I wonder if the RPM 4l60s hold up? Sorry OP, I know exactly how you feel.

I will never get rid of the C4 I love everything about a C4 too much; with the new trans I'm not planning on going crazy thrashing on it (I have other cars built for that). If I were going to crazy with track time in the C4 I would upgrade to a more current generation trans.
Down the road I would like to get a C7, the only thing I will do to that car is put gas in it and drive

Just fried the transmission
I changed back to the OD trans since I'm doing more highway driving.
