First of all thank you for reading and considering my problem!

History
Purchased a Ford E350 Diesel Van Drove for a week and it drove perfect
about to go on a small road trip and noticed my back lights had stopped working ,Replaced fuse everything again fine ,Went to hook up small trailer, Plugs different so had to change a couple of wires no problem drove for a couple of days pulling trailer no problem pulled into parking lot had to back into spot
Pulled forward fine reversed fine had to pull forward again nothing! Would not move an inch
In fact it felt like the transmission did not even engage checked tranny fluid looked good but about a quart low so I topped it up nothing
Looking underneath at the tranny noticed a small black box connected to link I think it’s a torque converter switch (Maybe)
So started van put in neutral disconnected harness to black box and van will drive to about 20 mph like normal but will not change gear and then retards like it’s not getting enough fuel...
Ok had a local mechanic look at it and he said that because the trailer wire was hooked up wrong it sent the wrong info to the tranny and killed it but why would it drive normal up to that point No slip nothing, and why will it work just fine if I disconnect the black box even if only in fist gear
My problem is this I would hate to put in a new tranny Quoted $2800
And then find out its something with the computer\
Now im no Mechanic but do enjoy doing my own maint on my trucks and I am mech minded and I can’t get away from thinking it’s the little black box not sending the correct info to my Tranny

Anyway sorry for the long story any help would be appreciated

Regards
