OK, so far so good, I'm glad to report.
Drove about 12 miles today...combination highway & around town. Shifts on time and smoothly. Yeah! Put 'er in 4WD too and no problems.
I also inspected the work area and under the hood.
Here's what was done: (the written bill of sale)
Remove, dissassemble, inspect, rebuild, reinstall transmission. Parts & Labor: $2049.18
Add external cooler: $140.00
Replace Rear main seal: $102.65
Enviro-shop fee: $25.00
Subtract: $100.00 for bringing in Terry Bradshaw coupon from Cottman website.

I'm a 70's and 80's Steelers fan too.
WARRANTY: 6 mos. - 6000 miles.
Going back in two weeks for a free "check-out" by the Cottman shop. Included in the deal.
Paid the bill and got a verbal recap of the work from the owner. Seems like a nice guy. (I'm being sincere)
Summary: Ok, pretty pricey job. But, if this lasts and remains as reliable as it has been, I'll be very happy. At 172k miles now. Would like it to go trouble-free for another 30k. Maybe wishful thinking?
Comment on the external cooler. I agreed with this option. The existing tranny fluid lines going through the radiator were removed and rerouted to a new finned cooler (heat exchanger) mounted on the front external face of the radiator. It's fairly big with lots of surface area. Remembering my Thermodynamics and Heat Transfer lessons, I'm comfortable with that. Also, having the tranny fluid next to ambient air has got to be better than hot radiator fluid. Q=hAdT
However, tie wraps were used in one area to support the new hoses to the external cooler. Will have to keep an eye on those or replace with something more solid.
I'll try to post some pics soon.
What do ya'll think? (Remember, I'm not set up to DIY this.)
