Question about GMC Jimmy

2 Answers I just replaced the transmission on this 97 Jimmy. I went through the floor to get at one of the bolts just behind the gas pedal. In the process I damaged the wire harness that runs to the plugs on the drivers side of the tranny where the shift cable hooks up. I know..."DUMB @ss!!" I hooked the wires back together after the trans was removed. Only thing is, there were 2 yellow, 2 pink, and 2 green that had no distinguishing markings. I had a 50/50 shot. I got the trans back in and now the key is stuck in the ignition and it won't shift. I have power to the windows and the gauges work when I turn the key. Looking at the wires going to the shifter, there is a green and a yellow. So I guess I was on the losing end of the 50/50 shot. What I did is first swapped the greens with no results. Switched the greens back and switched the yellows with no results also. So I then switched the greens again (last option) and still have nothing. I've read similar symptoms pointing to the ignition switch. But not sure if this is it since I seem to have more things powered then the other posts. So is anyone as dumb as me? Can anyone help?

No i have done worse in my time so your not alone bruv,i wouldnt even have bothered with taking a auto box out to start with ,they are just too expensive here its cheaper to buy another car ,a manual one --- now why did you cut the floor to start with ,i would have used my 3/8th drive socket set with lots of extensions ,cutting the floor would mean that the vehicle will not pass its annual mechanical vehicle test here ,now i have a funny feeling that the you put in a second hand junkyard gearbox and this is your problem ,it doesnt work ,if these wires are the same colour then chances are they can be connected anyway round ,like the ones on a O2 sensor .How about a nice diesel manual ford focus or a VW diesel manual ,50+ mpg how bad is that

Not familiar with Jimmy's except I can tell you never do trial and error with wires like that. You have signal wires that go to the ECM and TCM and can fry them if you touch the signal wire to anything shooting volts above 5v. My advice is get someone to tell you exactly which wire is which while you still have an ECM and TCM working if not already fried.

My 97 Saturn SL2 won't go past 30 mph. Even with

I guess my first question would be - are you saying it is slipping in 3rd gear ? If you push the gas pedal to the floor it should downshift into a lower gear.
If it is slipping, or not upshifting into 3rd gear, I'm afraid chances are the transmission is toast.
You can take it to a couple of shops for estimates but they will probably want to pull the pan and take a look inside.

I started My 2001 Jimmy and stepped on the gas. The pedal went to the floor and is stuck. The engine just revs and I'm afraid it's going to blow.

your throttle cable is getting stuck or either the butterfly inside your throttle body is stuck open. Check these and see if either can be freed.

97 Ram 1500 over revving until hitting 45 mpm

It sounds more like a cable or linkage sticking, and yes it is transmission related, sort of, just because of the high RPM before shifting. Spray all your cables good with lube, at throttle linkage, and get under and look where cable & linkages are at side of transmission, and spray them good too, and work them back & forth, to try & loosen them up. Truck shut off & in park when under it eh.!
Then work shifter back & forth, gas pedal to floor & up etc, to try & loosen things up. That may just cure your problem.
