Hi. Yes I did definitely know the transmission was shot before I purchased. It strikes me funny that it drove fine after I did a complete flush.
When I bought the car my scanner said there was a gear ratio problem with 2nd & reverse and maybe a stuck solenoid. I reset all the codes after a flush and they’ve not returned even though I’m having the same issue once again.
After pulling the pan (which didn’t have any particulate, so I imagine it was probably cleaned since it had recently been off) and pulling all the solenoids (a code I got said one was stuck open) cleaning them and putting them back and after a long long flush, it ran and drove like a new car, shifted just fine.
Now it shifts intermittently. I’m guessing most likely something burned up and got hot and/or shot seals, since the fluid was black. But still puzzled it was shifting fine for a few miles.
I’m tempted to pull it and tinker with it myself, I mean I have maybe $1700 into it at this time and I think a decent tran overhaul kit is about $200-300. Hate to go with a pull on iffy mileage.
I like to learn, but generally I don’t do internals. Where I live (on a remote island), there isn’t a tran shop other than the fix-it-all neighbor mechanics, which is why I am thinking about doing the repair myself.
Anyway, back in the day, I believe mechanics used to drop their dirty parts in a bucket of diesel to clean them up, same with oil changes and transmission flushes. I don’t mind Berryman B12, but that stuff dissolves rubber and bones.
In short, I did a flush with diesel (as I’ve done for 20 years without incident) and filled it with new tran fluid and it ran great. Now I think there might be some residual diesel left because I can still smell it, so I’m tempted to flush it one more time before I pull the tran.
Anyway, that’s where I’m at with my project.
Thank you for all the input.
