My only vehicle the trans blew a cooler line on the thruway (highway, 65MPH+) and lost 3rd/4th... this is only related to the trans because I am no longer in the auto parts/repair business and I need to find a wrencher near me, but I digress.
This vehicle is an Envoy XUV w/SLT trim that was loaded to the gills, about the only thing I can think of it is missing is Rain Sensing wipers. It has the UM8 Navigation system w/Bose and XM Radio, Electric Adjustable Pedals, etc. It now has only 77,2xx miles and I intend to keep it
These came stock with 3.73 gears, HOWEVER, the original buyer or dealer ordered 3.42 gears for some reason--I assume for highway driving. It has the LM4 aluminum 5.3L V8 and backing into my driveway is a little scary--if you feel like you need to move another 12-18 inches, you need to feather the pedal because the gear ratio makes you cover the distance more quickly than a 3.73 or 4.10.
So that brings me to the topic of the post. Which is easier? Which is cheaper?
a) having new gears, preferably 4.10's, installed properly in both the front & rear differentials? will 4.10's work with the 3.42 G80 unit or does it need a different carrier? I know very little about this rearend, I assume it's the 8.6. (sorry, I'm a 12-bolt '60's-'70's musclecar guy.)
b) finding good used or reman'ed differentials, front & rear, and installing the complete units
................................................
It's been a while since I did any wrenching on cars & trucks and my buddy who worked for beer died recently. I don't have a garage and live in the Northeast (Western NY) and am subject to bad weather. I'm getting old and have a bad back/leg and can't do much.
I know 3.73's will be a much easier conversion but I don't do any long trips and need to haul some compost or lumber every now & then and performance is more important than gas mileage right now. I'd like to concentrate on this cost/job, but I also will need a transmission job too, I'll save the trans & lines for another thread, but please comment on this one first. If anybody's available for work in WNY please let me know. Thanks for any help.
