    What to upgrade on 4L60E for robustness?

    You went with AAMCO the second time? Was that $2400?

    What to upgrade on 4L60E for robustness?

    If I were able to get a rebuild, I would have gone for the Raybestos cluch pack that is really highly regarded. $1900 to do it yourself is certainly a lot, so I may find it worth just getting a shop to do it so I can spare myself the inevitable headaches I will run into. I might give the PWM...

    What to upgrade on 4L60E for robustness?

    Good point, I actually did ask for it when I initially called the shop, and they mentioned their cheaper reman warranty is only obligated to be honored by them, but their more expensive option (which I don't want to go for) is $3100 and I can take it to any ATRA certified shop. That really sucks...

    What to upgrade on 4L60E for robustness?

    Hi JayArr! Thanks for commenting on this post. Reading your first few paragraphs made me realize that yes, I don't need to beef up my transmission since it already lasted this long. I am at almost 300k, so I would be more than happy if I at least got 100k more miles out of it, provided nothing...

    No way! I was looking at Mr. Shift's Transmission shop too. According to a review they used to go by a different name but it has the same owner. They seem super reputable, nice to find someone personally who can attest to their quality. Edit: fixed an error

    What to upgrade on 4L60E for robustness?

    You really think it could be my ignition switch? I actually just replaced it to throw a part at a no crank/start issue I had that I just fixed a few days ago. My issue seemed to get progressively worse where it was just slipping at first during 2-3 shifts then complete loss at 3rd where it...

    What to upgrade on 4L60E for robustness?

    I'm in Missouri, I have no idea why the site says I live in Colorado. Know of good shops there?

    05 Envoy XL 5.3 Won't Crank

    Automotive hell, sadly. I was towing my camry home on a dolly (~4100 load, far below what the envoy is rated for) and the 4L60E decided to show me how it earned its infamy. Check out my latest thread.

    05 Envoy XL 5.3 Won't Crank

    I just wanted to say thank you to everyone who provided input to help me figure out my no crank no start. Special thanks to mrrsm, TJBaker and Mooseman for constantly providing good advice. On to the next problem :)

    What to upgrade on 4L60E for robustness?

    Soon after I got my 05 Envoy XL Denali running after a painful DoD delete process and driving it back to my home 4.5 hours away (graduated and moved out of my college apartment) my transmission started slipping in 3rd gear, sometimes grabbing 4th gear. A little bit after that, I completely lost...

    05 Envoy XL 5.3 Won't Crank

    I'm seeing this too late now, but during my drive home (which ended up turning to hell) I decided to mess with it, and sure enough it was turned all the way down. It is weird how it randomly used to get dim and then brighten up, makes me think there is something wrong with my ambient light sensor.

    05 Envoy XL 5.3 Won't Crank

    So I could always see the PRNDL screen when the no crank issue was at its worst, and the DIC and the HVAC screens only came back on when I removed the comb. Then when I fixed the BCM wiring initially all 3 displays worked, but all of a sudden none of them work. On the other hand, I may have...

    05 Envoy XL 5.3 Won't Crank

    It was always towed with all wheels raised. It is 4wd but I couldn't put the tcase into neutral due to the power issues. The motor on the tcase makes noise when I shift it and the knob does show that it has shifted, so I'm confident it is fine. The first time I tried to get this towed I...

    05 Envoy XL 5.3 Won't Crank

    When I put it in drive once, it inched forward a little bit I put it back into park. Since then none of the gears did anything. Edit: to add on, the linkage is definitely fine since we’ve been able to put it in neutral for towing

    05 Envoy XL 5.3 Won't Crank

    I tightened my battery terminals even though they were pretty snug, and I reinserted the fuel pump relay because I wanted to prime the oiling system first and it started up. Forgot I had half the ignition coils disconnect so after getting those back in it’s even “smoother” now. The only issue...
