Get an Alto red band instead and a .292 or bigger intermediate/reverse valve.Any other suggestions?
an 88' is not computer controlled.:dunce:Crazy J said:a good start would be a Transgo shift reprogramming kit and rebuild it to V8 standards. if you have more money then get a performance rebuild kit, there are tons of these so i can't recommend one, but you'll easily find one that fits any budget.
and maybe a higher stall converter.
there are tons of mods available for these trannies but you don't really need any of them for a mild engine.
