6L90 REBUILD suggestions

Post by xtr366 » Tue Jan 26, 2021 7:55 am

Hi Guys.

Going into a 2013 express 2500 rebuild p0756 code .

Any suggestions on this REBUILD.
Im going with a complete master kit, steels and bond pistons . Ill be looking for common cracked piston .

Do you guys recommend a shift kit or only look through the tecm.

In 22 yrs this trans is the only one that scares me. Any suggestions would be great.

Thank you

It had 4 5 6 burned drum. We found a stuck compensator flow valve in vb.

We did a full master , sonax zip kit, pr valve pump update end caps update. Billet converter. New 1 2 3 4 piston .

Worked great.

Thanks
