727 transmission rebuild
Well I asked him last year what it would cost to have him remove and rebuild transmission and install. He said $1000. I asked how much I would save if I pulled tranny and installed myself. He said it would save me $300.
At the 1K price, it sounds about right. Prices can/will vary depending where you are. I spoke with a transmission shop owner I know and he said a total rebuild including re/re would run around $1200.00 excluding hard part damage(planetaries, pump) and of course any taxes, but would include all new friction plates, new steel plates were necessary, both bands, bushings, filter, converter etc. For $150.00 extra, he'd install the TF-SC shift kit. His price did not include an external transmission cooler.
You asked on one of your previous posts about a 2500 stall converter, or just the stock 340 converter. Unless you've been into the engine and are now making a lot more power than stock, go with the stock 340 converter. If you need a performance converter talk to one of the many converter builders that have been mentioned on this board. Give them all the information about what you done/installed to your engine, rear axle ratio, rear tire size and what your MAIN use of the car will be. Don't bs them about what you've done, or you'll end up with the wrong converter for sure.
There are exceptions of course, but over the years I was in the industry, most transmission shops knew little or nothing about performance converters.
