  • R & R Tech: Motorists May Know Something They Don’t Know
    Wednesday, August 1, 2018 12:00 AM
    As we see numerous cars come into our shops on a daily basis, we often have a diagnosis already in mind based on the customer’s complaint, the type of vehicle we’re working on, road test experience, and symptoms. That’s the benefit of specialized repair. Sometimes the actual in-depth diagnosis proves us right, and sometimes proves us dead wrong.
  • Programming Not Included - Did the original transmission really need to be replaced?
    Sunday, July 1, 2018 12:00 AM
    A customer recently brought his 2011 Ford F-150 into our facility after a general-repair shop (not a specialized transmission shop) had just installed a used transmission. His truck was a 4WD vehicle equipped with a 5.0L engine and 6R80 transmission. When the customer picked up the truck from the previous shop he was told that the transmission was installed and everything was fine, but it still needed to be programmed (the shop didn’t have the equipment to perform this important step).
  • Take a Moment to Analyze What’s Going on
    Friday, June 1, 2018 12:00 AM
    Too much play in shifter bushings, or sensor insufficiently sensitive - We’ve all had those days where you roll into the shop ready to start the day and see a car waiting for you there in the parking lot and think, “Well, that looks like trouble.” When I came in to find a 2005 Mini Cooper waiting for me, I felt my hopes for a peaceful morning wash away just little bit. 
  • Extra Set of Eyes Saves the Day

    In addition to the OEM-spec remanufactured transmissions we build, we also offer a series of heavy-duty transmissions available in three different stages. This article examines the installation of our Road Ripper™ 3000 (stage 3 unit) in a 2005 Dodge 2500 pickup equipped with a 5.9L diesel and a 618/48RE transmission.
  • ‘Rebuilt’ salvage-yard transmission, hmmm …
    Wednesday, January 3, 2018 3:45 PM
    We had a local general repair shop bring us a 2014 Jeep Grand Cherokee 3.6L V-6 engine equipped with a ZF 8-speed (845RE) transmission; they had just installed a “rebuilt” transmission that was sourced from a salvage yard. The customer’s stated concern was, “The place that built the transmission just said it needed to be programmed.” Needless to say, we knew that this was going to be an adventure.
  • R & R Tech: Overdrive Solenoid Déjà vu All Over Again
    Friday, December 1, 2017 12:01 AM
    About a month ago a customer came into our shop with a 2008 Chrysler Town & Country equipped with a 4.0 liter V6 engine and a 62TE transmission. He was complaining that it had a whining noise, and sometimes it would not shift and seemed to stay in the same gear. When the vehicle was hooked to the scan tool it had a code for the overdrive solenoid control circuit (P0760). The fluid was at the correct level and smelled like normal fluid; however, it was dark purple indicating possible metal contamination.

    Mike Greer’s advice: Don’t turn away an all-wheel Mini Cooper just because it seems too complicated.
  • Verify What the Scan Tool is Telling You
    Sunday, October 1, 2017 12:00 AM
    Every now and then we run across a vehicle that has a concern we have seen many times before and we almost automatically try to diagnose it by memory; it's almost like a reflex we develop over time. Of course as we all know too well, this can lead you down the wrong path if you stray away from complete testing and verification.
  • Understand Systems Involved in Diagnosis
    Wednesday, September 6, 2017 9:47 AM
    A while back we had a customer come into our shop stating, “The vehicle sometimes has a VSC (Vehicle Stability Control) error and won’t go past fourth gear, but today it seems fine.” The vehicle was a 2007 Lexus LS460 with 132,561 miles, and equipped with an AA80E 8-speed transmission and a 4.6L engine. As with routine diagnosis, I started with a road test, a scan of all modules, and an undercar inspection.
  • Blame it on Missing Harness Retaining Clips
    Monday, August 7, 2017 10:05 AM
    The subject vehicle that was fitted with one of our remanufactured transmissions six months prior showed up at one of our repair locations recently, with the customer concern of an intermittent bumpy 1-2 shift, and a low-power lugging sensation along with a CEL on. While performing our initial evaluation, we found a P1860 code stored in history, but not current. During the road test the truck was working well with no clear signs of what set the DTC, but after several minutes of driving it started to act up. The TCC was applying right on top of the 1-2 shift, but according to the scan-tool data, was not being commanded on by the ECU.
