I'm looking at a transmission that has a 26 or 27 input output spline count. What's the stock world class spline count for 89-92 tranny's? I've been told this is a stock GM WC t5. I've only dealt with 700r4's before so the t5 is a new beast. Thanks for info.

 

27 spline is stock correct for T 5, 4 speeds, three speeds, 700r4's 2004r's, th350's thm200c's, thm250's, PowerGlide;s and th375B's

th400 and 475 are not 27 output
are 32

good luck
