Hello all. New here. This may be discussed somewhere but I have not found it. Here goes.
My buddy, he's disabled, has a 1999 frontier XE 2.4L automatic. Transmission seals are dried out and letting fluid seep by when cold. It won't pick up gears, or shift good until it warms up. After it's warm, it works pretty well.
We were looking at getting a salvage transmission and installing. A transmission shop told him that he'd have to take to Nissan for them to reprogram the computer to the truck to get it to work. Is this true?
Who has had this issue? Why could we not plug and play exact transmission model?
Thanks for your help.

Why don't yall just grab the Transmission Control Module along with the replacement transmission?

He was told that it was a "computer" internally in the transmission, and that it would need to be programmed to the truck computer.

I perused the AT.PDF section of the FSM for my 04 and didn't see anything that would substantiate that claim.
But I recommend calling some other tranny shops to see what they say.

Gen 1 Frontiers don't require the trans to be programmed. That would be the case for a Gen 2 Frontier. The Gen 1 Frontier's TCM is under the dash and you don't need to do anything with it.

I've been looking to find a part number for the Gen1 TCM, and haven't been able to find one. I can find engine control modules, but not transmission. Does the same module pull both duties?

No, the ECM and TCM would be different modules. If you give me more info on your vehicle, I can try and help you find the number. I would need to know year (production date may be helpful, too), engine, trim, drivetrain configuration, body type (KC, Crew cab, etc.) and I may need to know the emissions certification (Federal or California spec).
