Stock Powerglide case cracking in the reverse curcuit

HR 9505 · 04-14-2016, 08:35 AM

I'm currently on my second stock powerglide case that has split or cracked in the reverse circuit and leaks bad when the transbrake is applied. I have run stock cases for years with no issues but I had one to crack last year and now this one. I know these cases are 40 years old and it's basically a crap shoot whether you got a good one or not. I was wondering if there is a main reason why these things crack in this area or could I have an alignment issue. I'm running a 3500# 55 wagon with a SBC 406 on alky running 6.30's and 40's wide open. Could I be at that fine line of power vs weight that could be causing this? Before I found another stock case, I wanted to see if going to an aftermarket case would be better fit?

Thanks in advance!
