While driving from vegas to my parents place in Cali my trans light came on I made it home and pulled codes. It had a 26 trans temp out of range, my auxilary temp guage said the trans was ok, so I pulled the trans conector and it was full of oil so I cleaned it put it back on light was out cleard the codes and went for a drive. Got half way where I was going and relised I had no OD then the check trans light came on turned around went back home checked codes and it had a 56 trans temp too high checked the conector again and relised I haddent gotten all the crud out waited for the parts stores to o0pen got some electrical parts cleaner cleaned it out real good drove it still no od and slipping in 1st got codes 56 91 #1 solinoid and 94 convertor solinoid, covertor was working fine. Pulled the conector again and made sure none of the pins were backing out cleared the codes and drove it 1st was slipping then 2 nd slip then whil parking it would barely move for a couple seconds pulled codes and got a 56 91 92 #2 solinoid 93 tcc solinoid and 99 epc solinoid I think the plug is lose and causing a bad conection because one of the clips is broken off and the other was damaged.

 

well I found the oring from the conector had come off and was holding the conector up so i fixed that and it got me back to the original 26 trans temp out of range but first gear still slips so I don't know what is going on, any ideas of things I can check how can check the trans temp sensor to see if it is bad?

 

Oil on the exterior pins will act as a insulator and cause issues. If there is no oil there I would drop the pan and see if its full of silver mud and shiny metal. Hate to say but it sounds like mine did before the tranny croaked.
