I noticed that if I run in 3rd gear alot, the trans leaks fluid out of the shifter tower onto the top of the trans and makes a mess of everything. I've drained and refilled the trans up to the bottom of the plug, (on rear cover). I haven't drove it enough to see if it does it in 1st or 2nd, but it does in 3rd after driving around the block.
I took the shifter apart, (couldn't get the lower cup out, with the "H" cut in it), and the only thing I did different was put the o-ring under the upper umbrella cup, it was on top under the lower spring retainer.
BTW . . . Got my headlights working. One of the PO's had hooked the violet wire from the switch, up to the "F" terminal of the regulator. Gsssshhhhhh.
I now have a flashing double yellow pancake light, a constant red light, (both work at full brightness on "DIM" & "BRT". And I have the white wire available to run a rear utility light at a future date.
