Post Replacing rear seals on a 700r4

How hard is it to replace a rear seal on a 700R4 tranny? mine was setting for quite a while and I think the seals are dryed out. I put some Lucas Transmisson conditioner in and it looks to be helping. The Tranny shifts smooth and all 4 gears feel great!

JD, don't be in a bigh rush to leap on your tranny. The GMs are famous for leaking after a long sit. The fluid leaks out of the torque convertor back into the pan, causing an over fill situation. The extra head pressure will cause the leakn normally from the tail shaft seal. Clean up the mess, drive the vehicle and see if the leak returns. I park my rods during the winter and put the drip pan under to catch the leakers.
