navion Posted June 27, 2004 Report Share Posted June 27, 2004 Problem: 4T80-E in 1994 SLS Codes P029 & P094 set. Transmission limited to 2nd gear limp home mode. Transmission fluid is clean with no abnormal odor. Inside of transmission looks very clean with the exception noted below. I dropped the transmission pan this morning and found three things: The first item that I noticed was in addition to normal clutch debris, there was some small flakes of a redish/orange material that resembled hi-temp RTV. This material was not present when I changed the fluid previously. I am hoping that it is the sealant from the torque converter seal that I replaced when I had the engine out last year. ( I installed a rebuilt torque convertor at that time.) The second item is that one of the solenoids mount base (white nylon part of the solenoid) was cracked which allowed the solenoid coil to swing away and disable it's self. This is probably the cause of the trouble codes P029 and P094. The third item that I noticed was that the solenoid screen assembly (item # 917 in fig. 17 lower control valve assembly) was pushed out against the base of the broken solenoid. Given all of the above, what I am trying to determine is: 1. Did the solenoid break on it's own, causing this problem? 2. Did the solenoid screen assembly somehow push on the solenoid causing the base to break? 3. Where did the red flakes come from? If anyone has some insight into these questions, please "E"mail me @ email@example.com . Thanks Britt Britt Link to comment Share on other sites More sharing options...
