Built 4L60E vs. TH400?
I'd think about the TH400 swap... and unless you REALLY need the gear vendors unit.. I'd skip that as well. A converter that's just right, and the right rear gear, and it's not as bad as everyone thinks. Besides... I don't think that the gear vendors will hodl up to that kind of power all to well either.
Unless you daily drive the car, or drive alot of long distance trips, a 2.73 geared TH400 setup on the street won't be that bad. And if you do daily the car... what on earth do you need 700 rwhp for LOL!
Th350's and 400's were stock transmissions in alot of cars.
Driving at 3000rpm on the highway is fine for you motor...There's no major load on it just cruising down the highway...It'll be just fine.
th-350 not bad in the city or the highway 4000rpm 70+mph but it will get old quick. We have a gearvendors holding 700 hp. the gas milage went from 10mpg highway to 16mpg with it. It bolts to the end of your transmissions outputshaft . thedriveshaft gets shortened also so its {stronger} . Only downfall is geting it to fit . We had to BFH the floor board .
as far as going with a 400, well i drive REALLY ******* FAST on the highway, like i cruize at 80-90mph so no lockup and no od is out of the question for me at this point. **** i drive faster than 60mph alot of the time.
can't go on replacing 4l60e's forever though, and im in the same boat as alot of these people- gonna buy a built trans SOON but don't know quite what yet...
The 2 trany's are soooo far apart in the power holding capability and THAT should be the MAIN thing considered when comparing these 2.

I recently went from 4l60e to TH400...I have full manual reverse valve body and a ratchet shifter. The combo works great. Fuel consumption is an issue. The 4l60e was built to be a kitty cat/feel good transmission. The Th400 is more like a freakin Puma. It shifts fast and hard.

That's why I bought mine
Do you guys do a 3800 stall or just 3500 and 4000?
