    Got a slight problem- my 3-2 kickdown soleboid is always on and has been causing some non existent shifts and like pressure being diverted. At parking lot speeds (10mph) and less than 10% throttle it will go through all 4 gears- but acts like it’s in overdrive at any higher throttle. When...

    4L80E temp often getting above 220-240 when climbing long mountain grades under load. What is the heat tolerance on these and how to proceed?

    Its a 1996 k3500 cheyenne ambulance with diesel. I assume its got the 4L80E. I climbed a short hill last year and it shot up above 240 quick. I changed the fluid it was dark and lot of metal on magnet but still operating fine. This winter I let it get to 240 at least 5-10 times for up to 20...

    Odd erratic shifts 4l60e 4x4

    Got some odd shifts occurring, thought I would ask the experts for a direction to look in. Vehicle is a 99 Sierra 1500 SLE 4x4 Currently the vehicle goes into all gear ranges manually and with ease. In D4 range it struggles to get into 2nd (high rpm) that needs me to get off the gas before it...

    4L60E sometimes acts like it's in neutral in reverse.

    1994 Chevy Silverado Extended Cab has a problem where reverse does nothing sometimes. The only fix is changing gear, then back into reverse to work. 183k miles on the odometer, so I'm wondering if it's just time for a replacement. Also, when I replaced the pan on the transmission a few thousand...

    H7B or M7B

    Clearing out our storage at work today and I found 2 brand new Tru-Cool oil coolers in their boxes. Boss said they were gonna get thrown out so I could take em. My question is should I use the M7 or the H7? I've heard the M7 is a direct fit, but seeing as I already have the larger H7 on hand...

    I have a 1997 Chevy C1500 a entirely bone stock truck, I was interested in changing out the OEM shallow pan with a PPE extra capacity pan. I wanted to see if anyone else has done this mod to the 4L60E and if so what are things I should be mindful of.

    Hi all. I have a '95 K1500 5.7 with the 4L60E that I have owned from new. It now has 198K miles and counting. All in all this truck has been well maintained (by myself) and had a pretty good life. It is mostly stock. The biggest problem is that I only put on about 1K miles per year since I...

    I've got a 94 Chevy k1500 with the 4l60e. I just got this truck moving. The previous owners disconnected pretty much everything to do with vacuum and electronics on this truck so I had to go through and redo everything. My issue is that the transmission slips really bad in first but the second...
