1989 FJ62. I bought it with 154,000 miles on it. It currently has 268,000 miles. When the tranny starts slipping, the Rodney flush has fixed it every time. I've done that twice since owning it. Recently I had an issue that was very interesting. My distributor G pickup coil had either moved, or something else moved and the rotor rubbed the pickup until wires were showing. The truck would drive but acted as if the timing was way off. It felt like retarded timing which would all be related to the distributor. However, at the same time, it shifted vary hard into all gears and hung up shifting to near redline. Now I don't know if these things could be related or is coincidence. Either way, I drained fluid to inspect/change filter and throttle/kickdown cable. I removed the valve body at the same time and noticed that gasket pieces on the valve body are brittle, cracking, and braking off. Since I didn't have those parts available I used a light amount of RTV gasket sealer on the places that were missing gasket and put it back together. Filled with ATF and took it for some test drives. Not fixed. Hard shifts and hanging up. I kept fiddling with the kickdown cable and adjusted the Throttle Positioning Sensor. I was being very sensitive to how it shifted on test drives and figured I should ask the wife to go for a ride to see what her impression was. Maybe it wasn't as bad as I thought and I was just being hyper sensitive to how it was working. Well, we were on our way to the mountain bike trails and the first 2 shifts were hard shock shifts. The third shift into the trip is miraculously fixed itself. (My wife is an energetic healer and she ran processes on it, so maybe she fixed it). I'm just wondering if timing can affect shifting? I know the manual says the engine should be isolated and running properly at operating temp to run the FSM tests.
I did order valve body gaskets for a valve body rebuild. My searches haven't found any posts for valve body rebuild. I've seen one for Rodney's Extreme Valve Body install. Does anyone have experience with this?
Thanks,
Pete
