D6R - 5LN02305
The machine has had an intermittent issue of shifting hard when you change directions. I did the fill calibration and it solved it for about 20 hours.
I knew that there was a newer style modulating valve to put in these older transmissions so we put the newer style in it and serviced the transmission by changing oil and filter. I recalibrated the trans fill and clutch engagement pressures and turned him loose again. This time it lasted 30 hours before shifting hard. Now I can recalibrate the trans fill and it will work perfect for 3 or 4 hours but usually goes to shifting hard again by lunch time.
I'm just wondering if there's a software update I need to upload in to it to solve this or if the calibration process is just masking a valve or seal issue temporarily.
