I have a TSI 1.80 planetary I have been running in a stock case for a couple years. Switched everything over to a TSI SFI case. 6 runs later lose reverse. Found reverse springs in the pan in pieces. Planetary had rubbed spring retaining plate . Had. 010 endplay with a bearing behind pump. Bearing is behind planetary also. The nuts on the axles rubbed. Any one see this before and suggestions on how to check this clearance.
