[QUOTE="Phil P, post: 5434136, member: 33598"] This procedure is performed at your own risk, no warranty is offered or implied, you may lose your house if you do not keep up repayments;) Right calibration, to start you’ll need to heat the transmission oil to at least 55 *c you can check this in the EPC address 36, it’s displayed in *c Park the tractor on level ground and select park and make sure the hand brake is off, enter diagnostics (technician mode) and set the rpm to 2100 Go to EPC address 37, this is to confirm oil type, you will need to enter and save it as 000 even though it will all ready show 000. (Once you start calibration DO NOT operate and ancillarys - pto, diff lock, mfwd, ac etc. It doesn’t matter if they are on but don’t cycle them) Then go to address EPC 38 (it will display cal) enter address, The display will then show “For” , move the f/r level into forward. After a shot time the display will change to “nEU” move the lever to neutral The display will then changed to “A” select A range. The display will then change to “For” again, move the f/r lever into forward again. The display will change to “F” while the forward clutch is calibrated (do nothing it will take a couple of minutes) The display will then change to “rEu” move the f/r lever to reverse The display will change to “R” while the reverse clutch is calibrated (do nothing it will take a couple of minutes) Once reverse is finished the display will change to “EOC” provided there’s no faults. Once “EOC” is displayed save the calibration (hazard lights on/off) knock revs off and restart tractor. Go for test drive. If it’s still not acceptable you may need someone with a laptop to tweak the calibration settings. If you get any faults during calibration it may display Some other letters Oil - check oil temp Spd- check engine rpm or ground speed detected H - pack pressure high L - pack pressure low There’s a load others but they’re the ones you may get.
