I have re-geared a boat loaf of jeeps and early 02-06 GM trucks and never had an issue, granted they have all been 4wd
Quick Google search says you need to reprogram it for the difference in gears using hp tuners or something equivalent.Sorry, in the sentence below "Got a question guys". It began with
Jr's 05 1500 2wd.
I guess I should have added that it is the 4 speed automatic, 4l60E.
I went and saw my Chevy truck tech guy. He said the speed sensor is on a shaft in the transmission on 2wd and in the transfer case on 4wd. He did not know of a way to get around that.
So I went to the transmission shop that just replaced his trans. Same thing. He said the part number is the same for that in the trans regardless of rear gear. He does not really do much modified stuff so he did not know a trick for it.
I believe 07 and newer trucks use a speed sensor on the rear axle.
Tire size does not matter since the trans is reading off the trans shaft. The ABS sees a speed difference in front and back and makes abs not work properly. I guess I learned a few things today.
There has got to be a way to run lower gears and keep the ABS happy?
Why not change them out now while it is nice outside rather than in the cold of winter?Snapped the nut off the tip of glow plus I’ll be waiting till next winter and I’ll change all 8 out using a shop after that snapping scare I won’t do glow plugs myself .. I used PB blaste for 48 hours also
I don’t think the tires are to blame here. Truck was still on factory 245s when I bought it. I went to a 285/75 which is almost 35x11 and have driven it 11k miles on them. Company truck is on the same size and has had a hell of lot rougher life than my duramax.Wide tires cause a whole world of problems 😂
