There is a mounting bracket that holds the two transmission cooling lines to the side of the bell housing.Vibration causes the bracket to wear through the steel wall of the lines.You may wish to remove this bracket and check out the lines before removing the entire transmission.

Something to think about if you pull the tranny yourself... 83 & 84 models have bolts and nuts to hold the starter (newer models have bolts that thread into the starter housing). You might want to unbolt the motor mounts and use a lift to manipulate the motor position. I didn't do this and broke the right motor mount causing it to slide back, down and to the left. Had to use a tow chain and a friend's truck to pull the motor back in position (in the dark) to be able to get the transmission to slide into place. Was still almost impossible to get the starter bolts back in with the bell housing so close to the firewall. Good luck.

The source of fluid leaks can be hard to pinpoint at first glance.

It maynot be coming from the grates, thats just one of the places it gets blown to.

I've always managed to fix my tranny leaks by retorquing the pan bolts. I always find several that are loose.

Use a torque wrench and torque them to (36 to 39 in-lb). Degrease everything, I use Simple Green and hose, and see what developes.

It may be engine oil from the rear main seal? Dan
