And now I have a 4th, and 5th option.
I call the guy that makes one of those adapters, and tell him my story. The first words out of his mouth were...” Why aren’t you using the A340 trans that came with the engine?”
Uhhhhhh...because I thought they were weak?
“An A 340 is no different than the 4l60e you’re talking about using, unless you open it up and replace some of the failure prone junk inside it, neither of them will live past 400-450 hp. But, open it up and change out the sprag and a few other parts, and it’ll reliably survive to 650 whp.”
I have an A 340 already ( provided the metal scrap truck hasn’t came in the last day, and gotten it from BMW where it has been sitting )
Itll need to be controlled by the ECU though...And it’ll need a converter, and an adapter to make a slip yoke driveshaft work ( they make an adapter, but i’d have to have my driveshaft converted to two piece)
Lastly,...( And i’ll have to choke on this because
@TOOLOW91 told me to do this) Sorry Jeff.
Use what I got. Buy that stinking 1000.00 adapter and a JW ultra bell. ( 4r70w to GM) Send my converter to PTC and have them cut it apart ( again) and adapt it to a GM pattern.
