I have a 2005 GTO that we converted from manual tranny to a 4L80E. Currently trying to calibrate the speedometer, but making changes to the speedometer pulses per mile, does not make any difference at all. Can someone help?
I have a 2005 GTO that we converted from manual tranny to a 4L80E. Currently trying to calibrate the speedometer, but making changes to the speedometer pulses per mile, does not make any difference at all. Can someone help?
can I make changes to the tranny gear settings / rear gear settings / tire size to maybe compensate for this?
the 4L80E is geared:
1st=2.48, 2ond=1.48, 3=1.0, 4th=.75, rev=2.07
my rear gear is: 3.46
My rear tire is 26.25
anyone?
I presume you have over-written your M6 calibration with an A4?
not that I am aware of. We are using a stand alone tcm controller made by pcs model tcm-2000 to control the 4L80E.Originally Posted by MNR-0
speedo now reads the correct mph, but it lags a bit
