TRNW TECH TIP
OF THE MONTH!
68RFE Pump and Converter
Watch out for the TCC accumulator valve clip!
68RFE Pump (click to enlarge)

68RFE, Potential Trap!
I just wanted to post this to give everyone a heads up, on leaving out the clip that separates the TCC accumulator valve from the other valve in that same bore. The truck was working fine when it left, CVI's were in specification, and no codes. However 2 hours later, the truck was on the side of the road on fire. Customer said it went to neutral, and looked in the mirror and saw smoke. He had a fire extinguisher to put out the fire, but not before it destroyed the transmission wiring harness and the fuel pressure sensor on the fuel rail.

Just make sure you do NOT forget to get this clip back in place.

    new feature!INTERACTIVE TECH TIPS & TECH DATA

    TRNW has just introduced a new feature to their website which allows technicians to add rebuilder tips, picture tips, and technical data for every transmission model. Members can vote on each rebuilder tip or picture tip with the results determining the placement of the tip. There is also an option for adding a comment to each rebuilder tip, and error control is built into the whole package allowing members to delete any tip that they created.

    Technical Data such as application charts, checkball locations, torque specifications, etc can now be added to the website by the members, and rebuilder "cheat sheets" can be printed out for technicians to take to the bench. A cheat sheet can be created, edited, and saved by each member by selecting from the list of current rebuilder tips, picture tips, and technical data for the desired transmission. The output is formatted nicely for printing.
