97 gmc Sonoma 4.3 automatic transmission,  rear  main seal replacement 

[richard wysong]

2wd automatic trans about 3.5 on a lift with all the proper tools and a tranny jack, add at least 2 for 4wd, on the ground is any ones guess. Rear main failure is sometimes caused by thrust bearing wear on the crankshaft so check that first to avoid unnecessary labor cuz if thats the case you will be pulling the engine not the trans
