Torque Converter
1995 Corvette Coupe. 46k Miles. Mods: Open Air lid with K&N filter. 1.6 Roller Rockers, 160 stat, Tune, Dana 44 with 3:54 gears, QA1 single adjustable shocks front and rear. Best ET 13.20 @105 on a M/T 275-40-17 drag radial. Best sixty foot 1.88. Looking to do an aftermarket torque converter over the winter. I know once torque converter is installed I will need the OBD1 Stall Wall issue addressed in the Tune.
Any and all thoughts and opinions are welcome. Thanks.

I've been running a Yank SS 3200 TC for the past 70,000 miles on my 95 although I don't track my car at all.
If you don't mind.... what is the Stall Wall Issue that you mention above?

OBD1 stall wall issue occurs when using a higher stall converter. It usually happens when doing a burn out prior to drag racing the car at the track. The VSS signal to the PCM is lost which then puts the vehicle in limp mode which will start the vehicle in second or third gear prior to staging the car. It can be remedied by using an OBD1 friendly tuning software Tunercat and remedied by having the PCM not read the VSS signal.

That what I'm going to put in my car (or the Vigilante), I've been told not to waste money on others that are cheaper. How do you like the 3200 stall in your car?

Thank you Bob
vette196: I have been very happy with mine. It has made my 3.07 A4 a blast to drive............ but my non highway gas mileage has gone down as the fun has gone up

I am upgrading to a 3.07 (from 2.59) and its an A4
My winter (and hopefully not Spring) project is LE2 ported & polished heads and intake, cam, 1.6RR, 30lbs inj.,LT headers and a tune.
What engine mods do you have?

I wouldn't if it were my money. That old a trans and if it breaks, it craps all into the TC so if it happens in 2 years of purchase of a Precision Industries one, you can have a free "restall" where they cut it apart and clean it and weld it back.
I have broken 700R4s that are stock way under 100K so..... Depends on whether you will push it once you get some mods or not. If you honestly think you won't, think again.

Go with a Circle D and stay away from the other junk.
Get you 60’s in the 1.6x range and then you will have a 12 sec car.
What does your 98 run?

Haven’t run the ‘98 with the LS3. The trans is a built 4L60E by RpM Transmissions in Indiana. I’m also running a Precision Industries Vigilante 3600 Stall Converter with a built RPM rear with 3:73 gears.
