    68RFE Locked shifts

    Probably not many on here running a 68RFE but I now have the ability to provide locked shifts on the 68RFE transmission.

    That is awesome to hear Jim! I assume you are able to do this through HP tuners, or is it with MM3? Willing to share how, or are you a tuner now?

    I can do locked shifts on the 68RFE for 2010-2012?s on HP Tuners, 2010-2018 on UDC Pro RT/Warp for the Smarty Touch and MM3 as well as 2010-2018 on EFI Live (if I were to ever get a FlashScan V2).

    I?ve been running locked shifts for some time now and I absolutely love it.

    Don?t know, never looked at the 65RFE. Post up your file and I?ll see if I can locate the transmission section.

    It?s fine, post it up and I can take a look and see if I can find the transmission section. If it?s anything like the 68RFE I could set your file to be able to have full lock shifts

    Locked shifts is as it implies, transmission torque converter stays locked up when shifts occur. The 48RE can be made to stay locked during shifts between 3rd and 4th so I?d imagine the 46RE is no different.
