Okay so here’s my issue.. was driving down the road a cpl of days ago and I started to feel first gear and only first gear would start to almost feel like it would slip a little half way through the gear but then would pick back up like normal. A cpl of days go by and come to find out I have a transcooler line break on me. When it broke I was doing about 35-40 next thing I know, truck revs out to almost the rev limiter. So I pulled off and fixed the line and filled the trans back up with fluid to the right level and took off. On my way home it would shift up to third then it would lose third and go back to second unless I punched the throttle. Then it would hit third but never shift into overdrive. I’m stumped. I’ve built and rebuilt several of these transmissions and typically I can diagnose the issue and fix it. But this one I don’t know man I’m lost with it. Anyone have any ideas?
