V8 4.2 auto to manual swap- Done, but something wrong with speedo.
I thought i won't have to ask this but my mind is stumped about this problem.
Had my v8 for a long time now, its third of my V8-ts and its bretty clean looking.
Had a chance to buy *donor* vehicle with 4.2 and 01E CMG transmission.
So, work began, i swapped almost everything from manual to my auto v8, including abs module (manual and auto are different).
Gearbox wiring loom etc, everything needed and went all the details with them.
Got it all running from first start, no needed to add jumper wires or everything and after first testrun, i had speedo problem.
if i'm driving 90km/h (By GPS) it shows me 50km/h in speedo, every showing on speedo is like minus 40km/h.
Hope that i explained correctly.
1 thing i could not exhange is instrument cluster, i have build and fitted 95 A8 instrument cluster, dont want to get rid of that.
