Actually, you stand to gain some, as the TH350 is more efficient than the 4L60E, and has less internal reciprocating weight.

The downside is the loss of an overdrive, and a taller 1st gear ratio (2.52 in the TH350 vs. 3.06 in the 4L60E).

I lost 30RWHP and gained 28 RWTQ switching from a T-56 to a TH400 If that helps any

[Edited]

Forgot I switched from a stock 10-bolt to a 9" with 4.11 gears at the same time. So there's a little power in that 30 that the 9" is eating as well
