I think I read that you are supposed to flush the transmission lines and the cooler before installing the new transmission. Sounds like that is what you are recommending here also? What did you find in filter and how did you use that information to prevent disaster? I've been wondering about this since I started this process, and although I'm a few months out from having the engine installed, I'm trying to learn all that I can right now. So your input is greatly appreciated!
Yeah, i had flushed the cooler lines out with just compressed air and since the radiator was out, i used my AC flush tool to flush forward and reverse on both the motor oil cooler side and the trans cooler side.
I might have just missed signs of back pressure/blockage.
My main focus was on the engine oil cooler side due to issues it had...
for the engine oil filter, I cut it open looking for excess metal.
expected to see some during break-in, but it should reduce after a while.
For me, it got worse.
And after i changed out the engine break-in oil to synthetic at about 1k miles, it got way worse.
cutting open the filter confirmed bearing material in the filter.
Back flushing the radiator trans cooler again, i removed metal pieces (caught with a rag).
I'm thinking my new converter might have had a little trash in it, or me running the engine for a sec with low transmission fluid might have damaged the pump and sent some metal into the cooler lines.
since it didn't seem to be an issue until after a while, i'm thinking there might have been a little trash in the converter.
With the apparent blockage in the transmission cooler lines, the only odd thing i noticed was a lack of engine breaking with the transmission in tow mode.
For the burned out thrust bearing, the only cause i can find was a possible blockage in the transmission, usually the cooler lines.
that causes a backup in the converter and will cause the converter to be shoved into the flywheel.
for the crap found in the cooler lines,
I'm not sure if that was related or not, but otherwise the transmission shifted fine.
right now, i have both trans coolers bypassed with some -6 an tubing i had on hand.
Once everything checks out, I'm buying a new radiator and front cooler.
I also bypassed the engine oil cooler for now, I don't trust the radiator.
