Re: TH700 is it worthy

According to GM's usage charts, the 700R4 is only slightly weaker than the TH-400, and only in shock loading...

Replace the center carrier bearing to the wider one used on corvettes and police cars.
Replace the 1st/ reverse sprague bearing with the stronger one. (B&M is one source)

I've been pushing 500 horse power and 500 torque through one in a blown shop truck we normally use as a tow vehicle for about 7 or 8 years now with no problems...
The tranny stood up enough to shear off an axle in a heavy 1/2 ton chevy with display trailer in tow...

The guys use them racing around here because of the deeper 1st gear, and the over drive just CAN'T hurt anything in a Jeep....
If they live in the 600-700 horse power door slammers around here (these guys are real fond of the 501 and larger chevys) they should live in a Jeep unless you think you are actually going to launch from brushed concrete... [img]images/icons/wink.gif[/img]

Chevy also bolted just about every kind of transfer case you can think of behind them, so no special adaptors needed, salvage yard or GM parts room and you are in business.
