I looked through past post, I didn't find anything in regards to this. The ARAP trans constraints and varaibles are very different then stock 89 code. I was woudering which bin is easier on the trans and far a heat build-up? I like the way the ARAP varaibles feel but don't want to bake the trans on every day driving. I haven't mastered the TCC varaibles yet, partly because I don't understand them fully. I am running a trans cooler. ------------------ 1988 L98 Vette Heads/no EGR SLP Headers/Y-Pipe ARAP bin

The only good cure for the 700R is using the one with the secondary valve body.
What kills trannies is heat, loose converters, soft oem shifting, and the lousy TCC materials are the main causes for 700R failures.
The cooler circuit is only applied when the TCC is applied.
The only way I got one to live, was with a non lock up converter, and the necessary changes for that.
The oem converters aren't meant to deal with WOT shifting, or engine loads.
