recieved the ATSG amnual on 722.3 transmissions today.
Looks very good
Also found this:
shift correction kit
Looks like something worth trying out and a chance to have some fun in the garage at the same time
I found a place here in sweden that has this kit avaliable too.
Is there anyone out there who have used one of these kits?¨
The worst that could happen is that the trans behaves worse than before and then it's just a matter of installing the old stuff back.
