727 ticking in park?

I bet that was a sick feeling limping home like that. Thanks for all your thoughts guys. It’s making me feel a bit better about it that we all have the same thoughts as to what it could be. Means it’s probably something simple and over looked during the install. A quick fix is my hope. I never used that brand of converter, and I’ve never used B&M for the shift kit, only Fairbanks or trans go for the kit so it had me worried. Beings it’s a buddy, if it’s my fowl up, it’s my dime to fix it. Just how I am.

I have not used those components per say! I prefer transgo kits but my converter was sorta a B&M. It is a chevy Vega 9” built by an ex B&M employee.
