Good afternoon everyone I'm looking to upgrade my transmission I currently have a RTO14613 I'm looking to put in a RTLO16913A would this be a direct fit or would I have to modify driveshaft and other stuff? Truck is a 1990 379 if that of any help.
I can not believe how difficult it is to find the measures online.
This isn't much help, but here is a past thread on this site about rto vs rtlo. RTO vs RTLO
