    4l60e no shift attempt to 3rd after rebuild

    Solution : To bring this full circle, I just got the trans back in for the 2nd time and it shifted perfectly 1-2-3-4!!! The check ball going into the 2/4 Servo seems to have been my root problem. Also, on those 6 miles of testing I appear to have worn .015 off the new frictions. My original...

    4l60e no shift attempt to 3rd after rebuild

    I did get the green o-ring changed and it was there when I started. It looks like the check-ball that goes into the 2/4 Servo was not seating. I poured ATF in and it flowed both into the Servo and the main housing. A tap with a punch and hammer seems to have fixed the seating. (Your thoughts...

    It definitely was not starting in 1st, but I'm un-sure if starting in 2nd or 3rd.

    4l60e no shift attempt to 3rd after rebuild

    I noticed another, maybe huge, clue last night. It looks like my brand new 3/4 steels got hot and I only drove for ~6miles. I thought the transmission was never giving the command to change from 2nd to 3rd gear. I'm now wondering if it is possible the 3/4 clutches were applying with the 2/4...

    When checking all valves to verify they moved freely all seemed like I expected except for this one. Which I believe is TCC regulation? It moves freely, but the spring is loose. I took it out and the spring is not broken so I assume this is normal?

    4l60e no shift attempt to 3rd after rebuild

    I thought the same thing, I actually spend a day checking this out. I was most suspicious of tearing a bit of insulation and having a short to ground causing Sol B to be stuck on. This was not the case. I don't have the scan tool, but used a multi-meter. I also thought there maybe a chance I...

    4l60e no shift attempt to 3rd after rebuild

    Hello, I have just completed my first automatic transmission rebuild, and while I felt good about all the steps it now will shift 1st to 2nd, but never attempt to shift into 3rd gear. (Never attempts 4th either, but I assume this is because it never gets to 3rd.) Backstory: I have a 1995 K1500...
