The reason you need the manual transmission ecu is with the auto ecu the truck will run rich. I helped Allen put his tranny in, it was a job to do the first time but to do it again wouldn't be bad. I think he'd agree with that. The origanal holes for the auto trans wasn't big enough for the W56 with top shift he put in so with the help of a saws-all it fit just fine. To make it look descent too your going to need the center console and and arm rest. Also your going to have to find the neutral switch wire and ground it out so the computer will think the clutch is in and will allow it to start. Kind of a pregnant dog to do but he loves the manual.
