Not sure if im posting in the right area.

Heres my issue, I have a Art Carr built TF904 (2wd)with full manual valve body, reverse pattern with Art Carr shifter.

I cant get the jeepspeed to go in to reverse. If the jeep is rolling and i shift fast from 1st to reverse the trans will grab reverse but not hold it.

I've disconnected the shift linkage and shifted by hand with the same results.

Anything I can try next that im not thinking of before removing the trans from the jeep?
