Re: th400 with gear vendors overdrive I got one, good stuff. Check out the thread 'a firebird GTA the way they should have built it https://cimg5.ibsrv.net/gimg/www.thi...ce8b82e356.jpg this fit with no changes to the tunnel, and an unchanged TH400 crossmember |
Re: th400 with gear vendors overdrive I have one behind my 700r4 in my 2nd gen. Im telling you, there is NOTHING like having an effectively 8 speed transmission behind a ~400 hp V8. Not so much for drag racing it per se, but having these extra gears to downshift into at any speed. So worth the money... Then with the double overdrive and 3.42's the gas mileage is phenomenal. Even at 90 mph I'm only doing like 2200 rpm... lol. That said, it takes some practice to time the upshifts. Also if you get a shift knob with a button to activate the GV (which is what I did) itll be A LOT better and more fun than the foot switch. Lastly be aware it's a firm shift. The tighter the converter the more firm it is. But like I said earlier, if you time the activation just right, you can often mitigate most of that. It's not to the point of being objectionable (I have a 2500 rpm stall) but it feels like a good shift kit. |
Re: th400 with gear vendors overdrive There was a GV OD after a TH400 in the 1988 and 1989 Callaway Corvettes which were built under RPO B2K in the model years 1987-1991. Automatics were available only those two years, and had an external kickdown switch on the throttle body. It was a very slick install. |
Re: th400 with gear vendors overdrive Used a few in trucks and MH's I've had, behind TH400's and C6's, super stout, not sure you can break them. My first was manually selected, later ones with a fancy control panel. All worked well. |
