I'll try to stick just to the important stuff to make this as short a read as possible. '97 E40D with about 120 on a stock type rebuild/update. Truck has been babied and trans always shifted smooth and solid. Last weekend we hauled our horse trailer an hour away and everything was fine. When we went to leave some hours later I put it in reverse and the TC
was completely locked up...killed the engine. Did that every time I put it in reverse about 10 times in a row unless I stayed off the brake and gave it some right pedal.
Got 15 minutes back toward home, stopped for fuel, and noticed a puddle under the bellhousing. Started it, checked fluid level and it was fine. Looked under the truck and had a steady stream running out of the bellhousing so I shut it off and called a wrecker.
By the time the wrecker got there, I went to back the truck up and the TC
acted normal with no fluid running out.
Next day I took the truck for a test drive, and everything seemed fine for the most part. Worked the tranny pretty hard and got it up to 185deg. Got home and put my hand on the cooler...it was cold. Bypassed the stock cooler, blew out the aftermarket cooler, hooked the lines up and felt heat immediately after starting the engine.
I was in the driveway messing with the truck put it in park for a few minutes while I pondered the situation, went to put it in reverse...nothing. Put it in drive...nothing. Shut it off, restarted it, had drive and reverse back. Put it in park for a minute...no drive or reverse.
This morning I decided to take the truck out to see what it would do on the road. I had no converter lockup (torque app showed 0 on slip, but I hadn't looked at that before so I don't know if it was working or not).
Got farther down the road and went up a big hill. More and more slipping, until I got to the top of the hill, stopped, went to pull out and had nothing. Shut it off, restarted, and I was moving again.
At this point I could go 200 yards and have nearly no trans, shut it off, and it did alright minus the TC
until the next 200 yards. I limped home, shut it off, got in my '95, and went to work.
, it wasn't until this morning that I got a P1728 code.
Anyone have any thoughts? I'm thinking rebuild time, but I want to try and pinpoint any issues before the trans gets pulled.
