If you only patched I doubt if you could have reversed the system. you could have a clogged line wheel cylinder or caliper.

Most likely a problem with the passenger seat sensor, BUT you always start by getting the trouble code from the computer. Otherwise you're just guessing.

Take the door panel back off and work the handle and see what is going on. There may be a adjustment or a sleeve the linkage came out of.

You need to find out which system is causing it first. Lift it and run it like that, get some help and find the source of the shudder

Probably a temperature sensor making the engine controller think it is hot and making the fuel very lean. Or, if old school, automatic choke is stuck off.

THe 4l60 is an electronic produced shift trany, It sounds like the place to start, is to see if you can shift it manually. Starting out in first and work your way up as the vehile speed increases. I have a question for you. Did this problem occur all at once or over time? I would say most common reason is shift solinoid problem, But could be many other reasons like, sticking valve in valvebody, bent or worn linkage, improper fliud pressure to pistons, etc. with your help and imput we can probably narrow the problems solution down.
