What operations do the valve body and TECHM mostly control? Forgive my ignorance and lack of initial research but figured I would post that while I look it up. I plan on having a trans shop or two take a look and give me their opinion just debating if and when I can tackle the fluid and filter myself or have a shop do it in case of other issues. First is getting my tires dealt with and then we’ll figure out trans or the hoses I need to replace (see my other thread about my trip back from Florida).if you are lucky you can just throw a rebuilt valve body/techm in it and cross your fingers, it's not a super easy fix like the 4l60's are.
not sure what he is working on there but I think you would need to drop the exhaust also
