6L90 getting low range
Hi guys,
I have a Nissan Patrol that I've swapped a 6.5 diesel and 6L90 into.
The trans is working well, shifting and all that, however, the trans came out of a LSA 6.2 petrol engine car, and obviously has the petrol car's trans cal.
I have that cars shifter, which has provision for TUTD which I'd like to keep.
Now that its in a 4X4, it has a transfercase with a low range.
What are my potions to get the trans to recognise the transfer case with a 2.86 : 1 reduction in low range?
The transfercase does output a signal when in low range, but the transmission tune has no provision for a low range.
Can this be "added" or is there a work around for this.
Hope this makes sense, as everything so far has been working really well.

in a factory setup it's actually the ecu that get's a triggered input for low range not the transmission.
*it may be possible* but there is some switches that enable 4wd mode. might need to source a factory 4wd 6l90 file for testing.
Im guessing your using the PCS controller, if so u should be able to wire the transfer case to pcs controller on digital input 5, change the software from Calibration B to 4WD Low, set to toggle & set active high or low depending on if it's power or gnd.
