I was wondering if a new torque converter will give the Suburban more power in the low rpm.
Does anyone have any experience with this?
Now the Suburban makes a lot of rpm but that’s it :wink:

How high does the engine rev? at around 65mph Im only turning over about 1500 if I remember right.

Mine too, but it’s the acceleration that sucks.
I have a 1000 rpm gap before it will start to accelerate.
Driving on the highway and cruising no problem.

Rear axel ratio has more to do with acceleration than the torque converter. Unless you have a slippage problem, or the trany is low on fluid. The axel ratios are so low in these the problem in acceleration is that you have a 3 ton truck and unless you have a 454 engine you don’t have a lot of HP.

My rear axel ratio is 3.42.
I don’t know if it’s for towing or cruising.
I don’t know what the ratios mean
