Question's for 4L60E owners...
 

-Does anyone have timeslips before and after installing a torque converter?
-Does anyone have timeslips before and after installing a new ring and pinion gear?
-What rpm's are you pulling with your new ring and pinion gear?
-And at what speeds (60, 75, 90, 100mph, etc...)?


-Any bits of information concerning the questions above would be appreciated.

(If you post any replies to these questions, please include a list of your mods!)

With: 3.73's, lid and M/T ET streets — 8.35 @ 85mph
After 4000 stall converter — 7.70 @ 87mph

Through the 1/4 traps I'm up around 5400rpm w/ a 26" tall tire.
