It's been a while, but I have a question for those of you with auxillary transmissions behind the E4OD. I'm looking at another IDI with the E4OD and 4.10s, being a dually I want to keep the 4.10s, and the auto in it was replaced 3500 miles ago, so I don't really want to do another ZF5 swap yet (the wife also likes autos). But when I'm on the interstate I usually drive 80-85, so my question is, does the transmissions computer get confused when the auxillary shifts gears?
