Billet Servo Installation

That certainly seems to make more sense as to why the new pin was too long. Just say screw it and go for the 80e

Trucks brand new...just over 11k miles on it

I'm sure I'll do the 4l80e when I grenade this one

Put some miles on the truck today and really like the way the truck goes with the converter and the servos! Only one thing I noticed that I didn't like is that I was stuck behind a couple cars and was cruising in od at around 50(about 1300rpms) and the tach was fluctuating from 1300-1500 but I couldn't feel anything funny in the way it was driving!? Anyone else have this happen?

was the converter locked? On some tunes its not locked until about 55 mph.

I know it was still in od but i dont think it was locked but not sure

I would NEVER grind or otherwise modify the pin length on a trans that worked properly before servo PISTON replacement. That makes no sense. It does mean something was not assembled correctly.

Then reuse the original pin. If the band is worn it needs replaced. The friction material on the band is 1/16" or so thick so when it's toast, it's toast.

Keep one thing in mind, replacement servos might not necessarily have the same dimensions as the OE servos. With that being said the band clearance should always be checked and or adjusted. Back in the day when I built stock units, we would still adjust the band. Even in this case remember that bands not only wear but stretch to a degree. Thus the reason why I feel when doing this type of mod or repair it needs to be addressed.

I'm going to guess that it was cycling out of lock up. With the new converter you might need tune for it. Vince B

Stretched, worn, whatever still needs replaced. A novice messing with apply pin length is no solution.
