4T65E HD Diff Gears Breaking Apart
First of all
About 3 months back, along story short, i converted the trans from non HD to HD.
About two weeks ago my trans started to delay shift while transitioning to shift up to next gears on a few occasions, to the point of getting past the rev limiter i believe at around 6700 rpm, and if i went to WOT, it was slipping.
About 1 week ago it started getting more frequently very fast then would not engage any gear at all 1-2-3-4 and reverse, unless i turned the car off and turned it back on and still only lasted for about 10 seconds.
So i tore it down and found what appeared to be small pieces of gears in the bottom of the pan, but no sparkles or metal flakes in the oil. I completely tore down all the clutch assembly's and no leopard spotting, no burnt clutches, no bad bearings, and chain and gear-set all looked good.
Then took out the diff assembly and there it was! Final drive ring, sun, and the 4 smaller gears that mesh with the sun gear were all chipped up. So i imagine the tcc solenoid is plugged with debris.
I kinda feel stupid asking this, but did i forget something when i did my swap?
