Does this tranny have a lock-up converter when used in a 3/4 ton? When I touch the brake, I don't see the 200 rpm rise like in my 700R4 gas truck in 3rd or 4th gear.
Also,
Is there a decent tranny controller for this vehicle? 1998 Suburban Ls 2500. I'm also looking for a computer chip replacement for it. I'm trying to enhance performance when needed and get the economy when I don't.
To get better fuel economy, does it make more sense to change ring and pinion Or:
get an overdrive unit from gear vendors or dual range?
THanks,
