auto trans lockup working?

Postby eriemc [OP] » August 3rd 2019, 8:06pm

I recently had to do a tranny swap on my 91 RWD shorty. the donor came out of a s10 pickup. seems to work fine but I can't tell whether or not the lockup engages. How do I tell?

Put the trans in manual 3rd. Drive with a steady throttle. You should feel 3 "bumps" = 1 - bump - 2 - bump - 3 - bump (lockup).
