No movement after 97 4l60e warms I just rebuilt a 97 4l60e transmission in a Z71. I replaced all steels, frictions, bearings and seals. I replaced all soleniods, and harness, I also replaced shift kit, and rebuilt pump. The only major part that I kept and used was the TC. The trans will go in to R&D, but will not shift past 1st gear,as the trans warms up I stop moving. If I turn the truck off for a min or two it will move a few hundred feet and then lose forward movement again. Is this a bad TC or something else. |
One way to determine if the TC is faulty is to test if Reverse works as forward and reverse have little in common, other than the pump and a few hard parts. However, I suspect you do have a pump/pressure problem as pressure goes down as the trans warms up. You need to connect a pressure gauge to the trans; such a gauge is about $45 on ebay or have your local trans shop hook one up. Did you remember the screen/filter on the side of the pump? Did you remember the o-ring under the rotor? |
After it warms up I get nothing no R or D. |

Thank you I will get it checked and let you know what I found. |
We just had another thread where the OP reported intermittently losing all gears and it turned out to be a collapsed trans filter: https://ls1tech.com/forums/automatic...came-back.html This is probably not your issue, but I like to point out the easy $10 fix even if there is only a 1% probability. |
