I swear I've sen this but I cant find it, so here goes.

The trans in the 87 R10 is having issues. Late on the first 1-2 shift of the day, TCC goes in and out when she gets hot and it likes to weep a little in the front - I'm thinking front seal and those pesky shaft rings. Truck is probably not worth the price of a rebuilt trans.

Picked up a 4L60 (700r4), out of a 92 C10, 15k on a supposed GM rebuild. K case turned 2wd. Truck it was in was totalled but driveshaft was not bent and trans case appears fine. Trans has set in the garage for about a year. To use it I need to swap some wiring (TCC on diesel is pressure / speed controlled not ECM controlled), TV cable (diesel is different length) and governer.

My question is, since it has been sitting and I ahve it out, what seals shoudl I replace? Pan, filter, and governer reseal are on the list. What about front and rear, and possibly dipstick seal? Or should I just throw it in and drive it?

As always, thanks for your support.
