is there such a thing as a lock up converter for at542 allison transmission? if not, can i change the whole transmission to a 643 or something comparable with no major problems?
There were a few AT1542 and AT1545 transmissions made. They only had lockup in fourth gear, I think.
However, lots of motorhomes with the AT have been changed to MT643s. If you want to invest the money, it's a good conversion.
Industrial Automatic Transmission in Irving, Texas has done a bunch of them. It's been a long time since I talked to them, but my experience with them was always good. They have been purchased by Inland Truck Parts. Their contact info is: 2339 East Grauwyler Road
