I'm Awesome
3 years ago Bought our '94 GMC k1500 to tow our 28' TrailCruiser that only weighs 5,000 lbs loaded. Was a one owner, always garaged crème puff, however 350 sucked, still had original plugs, wires, cap & rotor at 126,000 miles. Would barely go 65 mph and wouldn't tow till I removed original air cleaner setup and ran two 4" cold air intakes, MSD adjustable timing control, Fastchip and dual exhausts. Still wasn't acceptable so just had a new 383 stroker installed. Can't believe the torque. Found that the new engine didn't like running a high rpms in 3rd while towing, so put in 4th and it just settled in and ran easy, didn't hunt or have to shift down or unlock torque converter until going up steep hills. (Burb is an SLE with complete tow package, trans & oil coolers etc.)
So, the question is, is that going to hurt the 4L60e? Shifts good and didn't get hot on our 600 mile trip. The prior owner kept the fluids changed as required, we have the Carfax. Tranny fluid was flushed at 121,000 miles, now has 163,000. Should I have it flushed again at 40,000 miles?
As a long time RV'er, I know that the tranny is the weak point in any towing drive train, just haven't had any experience with the 4L60 so am looking for guidance. Used to tow with 1965 Chevy Van, 292-TH350 and an '88 Burb with 454..
