Erratic Shifting of the Automatic Transmission on Chevrolet Monte Carlo

Problem Description and Possible Solution

The transmission pressure control solenoid may fail causing erratic shifting. Our technicians tell us that partial dis-assembly of the transmission is necessary to replace a failed pressure control solenoid.

My car won't grab drive gear but it does grab reverse, neutral, second, first gear
had the transmission fluid and filter changed in my 2000 monte carlo now it hesitates and shifts hard from drive to 2nd gear only.HELP PLEASE.
Starting at a stop light, it jumps from first into second. Like a slip. When changing into third or fourth(whatever the last gear is) it makes a little skip. sometimes the starting from stop, it CLUNKS loudly. transmission fluid changed, but still does it.
Lately, the car is having large difficulties shifting, or won't shift at all. We replaced the transmission filter, and got more transmission fluid, but it still has a hard time with shifts when it's exceptionally cold outside.
Trans jerks when shifting.
New transmission solenoids.
Purchased car from fellow employee. Had all fluids and filters replaced, etc. Tranny fluid was clear when replaced. But continued to have problems where I'd start the car, shift into Drive and car would lurch forward HARD. Same happened at stop lights at times. Had engine checked for codes by mechanic. Car eventually would not shift at all. Had trannie taken apart and all solenoids replaced ( some were burnt out by this point). Within 2 days problems started again. Had used transmission put in-- 5 months of city driving later this transmission went. The car is now sitting at a repair station in PA. Is there anything that might be causing this issue other than the transmission?? Thank you!!
Trans will engage into gear at and shift sometimes fine but recently it disengages when in high gear. I can manually shift it sometimes it works sometimes it doesn't. I'm a mechanic myself and figured that it's still shifting so it's not all the way out . I changed fluid and filter and drove for 2 weeks then the problem came again
don,t go n overdrive
SOMETIMES, sitting at stop, transmission CLUNKS, and goes into second. I told repair shop it sounds like the bands are slipping; he said , tthis transmission does not have "bands" like the old cars.
The pressure solenoid went out on my monte at 88500 miles. shifting became erratic and eventually it failed to shift at all. complete rebuild had to be accomplished due to over pressures screwing everything else up.
car seems like it's jerking when it shifts.
My check engine light came on and my car won't change gears
I bought this car used with 100000 on it. The day I drove it off the lot it started shifting harshly accelerating and decelerating. I ended up getting the Pressure Control Solenoid replaced and that solved the problem. Now at 125,000 mi I am experiencing a different problem with erract shifting and I am hoping its not going to cost me another $700.
Car dont move our when put in drive our any other gear but when put in drive you can hear it shift.
Hard shifting. Smooth at takeoff but hesitates to go in gear after stopped.
I have to start out in first gear then shift to second and then it'll go into drive and Overdrive
Studders when shifts bangs and lost power up hill. Just started had fluid and screen changed 2 months ago no problems 4 th time filter changed since new.
X Wife had transmission flushed, sand that pushes all the clutch debris through out the transmission and clogs the shifting plate inside the transmission. Took to shop they fixed it for1300.00, where it lasted only a year and now wont go any where without dumping transmission oil all over the ground. So my solution now is forget about a shop and I will due it myself so I know it gets done right!
Stuck on

Torque converter is on all the time
What's the cost to fix ,
