Allright. I know alot of people have done this swap, and i’ve done alot of reading of those threads, but i still have a couple of questions.
I have two 1990 cars. an automatic LS and a 5 speed GS. how many of you guys that have done this just swapped out the transmission vs the whole engine/trans assembly. I plan on doing the whole assembly as I just swapped a 90K mile motor into the GS before i took a curb at enough speed to torque the frame pretty bad. the LA has 126K. Are there any differences in the wiring harness for the engine?
Also, when you swap the ecu from AT to MT is this just a plug in deal? or do you have to do some wiring changed at the ecu? I know the “can’t start unless in park” has to be wired to the clutch pedal switch, and the ignition keylock has to be jumpered. also i recall the reverse light has to be done a certain way to. so yeah, you just unplug the AT ecu and plug in the MT ecu? and what do you do with the TCM? just unplug it, toss it out, and leave the wiring? Wiring is my weakness in automotive repair, so I’d definatly appreciate the advice.
I’d also really like to do a really nice write-up including a complete list of what tools you need when for what. I know this may seem like overkill, but if the helms manual had that in it, all of us would’ve had sooo much time saved in just crawling out from under the car to grab the socket you actually need than the one you thought you needed, just to crawl back under the car. I KNOW everyone hates that.
