TRNW TECH TIP
OF THE MONTH!
Mis-machined 4L60E parts
Watch out for aftermarket parts that aren't machined properly!
4L60E Rev Input Drum (click to enlarge)

Poor Quality Aftermarket Parts!
I thought I would put out a warning on one of these after market drums. I had a unit I rebuilt and installed and had no reverse. I removed the unit and checked my seals on the pump for the reverse input drum. All ok. then I finally found the problem. As you can see in the pictures the hole for the drum was drilled off location. The bronze bushing drum has the hole in the right spot, the other drum the hole is in the spot that the sealing ring rides. The picture has the box it came in. There is nothing to show the distributor. - more

    new feature!NEW INTERACTIVE VACUUM TESTING INFORMATION & UPDATED HARD-TO-FIND PART #'S

    TRNW has just introduced a new feature to the web-site which allows technicians to add vacuum testing information and hard to find part numbers for every transmission model! TRNW members now have the ability to upload their own pictures and vacuum test data to have it displayed on the web-site for future reference! TRNW members can access this data and use it as a comparison for their own readings, or they can use it as a guide to help them determine where to vacuum test, and also help identify the common valve bore wear area's for every transmission! There is also an option available allowing TRNW members to post their vacuum test information on one of our e-mail forums as it is displayed on the web-site. Other members are immediately alerted to the availability of new vacuum test information!

    The Hard-to-Find Part Numbers area of the TRNW web-site has recently been updated. All of the existing information has been stored into a database for improved search capabilities and faster overall performance. TRNW members can finally submit their own part numbers and have them saved on the web-site for future reference as well! This should contribute to a far more adequate technical reference.
