have you checked for any PCM updates for this problem, even though its a 95. how about talking to someone at a trans shop to see if they have come across this problem.

That could be a perfect reason to take it back to the shop where it was just repaired for repeat service. Either that or you spun out in the mud.

there is actuators for each gear i would look into testing those

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.

I don't think its plug wires. When you say it won't shift into 1st? It takes off in 2nd? Does it shift to 3rd and 4th? Or is it a shifter problem? Like it won't go into manual 1st

• No 3rd or 4th gear: “3-4” clutches are worn out. R&R. The car is safe to drive (in 2) until you can get it fixed.
• Trans shifts into gear harshly, car feels sluggish off the line, No 1st, 4th or TCC lockup available, Manual 2nd, 3rd and Reverse are only available gears, CEL is on: Transmission is either in limp-home mode or has lost electrical power. If there are lots of error codes in the PCM, check the under hood fuse that powers the transmission, and if it pops again, look for a short in that circuit like an O2 sensor harness touching exhaust. Otherwise, check PCM codes for a particular fault in the transmission causing the PCM to put it in limp-home mode.
• No 1st or 4th available; trans shifts 2nd to 3rd by itself in D or OD and locks the converter : Shift A solenoid failed. Easy fix in the pan. Or a wiring problem from PCM to trans.. or PCM.

Check to see if your transmission is in the limp mode, which would only give you 2nd, 3rd and reverse gears. No 1st or 4th gear.

It sounds like your torque converter or the pump is broken.
