I ended up buying a corrected valve body with the sonnax tcc regulator valve fix thinking that would be the issue and threw it in the and to my surprise the harsh shift came back 30-40 miles after… Only codes I have in it are P0332, P0327(knock sensors) and a non confirmed P0748 (transmission fluid pressure solenoid - Electrical). I then read that maybe it is the throttle position sensor but dismissed that when I plugged my obd II reader in and watched the throttle position and saw that it was working fine (Same thing with the MAF sensor). I was excited to try her out again only to find it still does the same thing. I started off by dropping the pan and replacing the epc solenoid and did a fluid and filter change at the same time. Failure to Downshift The 4L60E will often fail to downshift if one or more of the shift solenoids are stuck open or closed. It does have a shift kit installed in it but the previous owner says that it shifted smooth/normally right after installation and started to shift hard when he attempted to drive from California to North Dakota. Here are the main symptoms of a bad 4L60E shift solenoid. They assured it wasnt the transmission cuz 'they dyno test them'. I called them and told them of the problem. From day one it has had horrible shift flare when going from 2nd to 3rd. I bought it knowing it had this issue and got a decent deal because of it but I am now a little bit challenged on what may be actually causing the harsh shift… The transmission was rebuilt and only has about 20,000 miles on it so I thought I would be safe from finding any major damage this early after a rebuild. Bought a rebuilt one from a transmission shop and installed myself. It is common for similar vehicles to have multiple transmission options available from the factory.Looking for help/ a point in the right direction on my 01 silverado with a harsh shift It shifts hardest from 1st to second and then shifts smoother every shift after that and if I pull over and shut it down for a few minutes it shifts smooth for the rest of the drive and comes back the next time I drive it. These transmissions can be found in the following vehicles however you should double check your application with the 16 bolt pan count.

The 4L60-E was found in the full range of General Motors vehicles including, Buick, Cadillac, Chevrolet, GMC, Hummer, Isuzu, Oldsmobile, Pontiac, and SAAB. The 4L60E will have a round plug with 11 wires. The non-electric shift will have a square wire plug with 2-4 wires. If unsure of your model, the 4L60E can be differentiated by looking at the wire plug going into the transmission. 1992-1993 are cross-over years, so your vehicle could have the earlier non-electronic transmission instead. New master shift solenoid and electronics kit for the 1993-up GM 4L60E 4L65E 4L70E 4L75E M30 automatic transmission. The 4L60E and its variants were in production from 1992-2013 and can be identified by the square 16 bolt oil pan and 4 forward gears. This kit comes with all of the electronics inside the pan. This shift solenoid and electronics kit includes:
