2004 Cadillac CTS won't go into gear -

What do you mean it doesn't accelerate? Will it accelerate at all, like gradually build up speed when driving? Or do you mean it doesn't drive at all? Does it rev while in neutral/park or out of gear?

From what you are describing, it is possible either the 3-4 actuator is no longer playing with the 3rd & 4th clutch packs, only way to know for certain is to hook up the good ol' pressure gauge to trans. system, yeah, you think the Chevrolet dealer should know this right?

Sell it now if you can!

well darla, im afraid you need new knee's!!LOL well ya need another transmission from a wreckers and if have access to a garage and toools and know how u might as well just get another engine and transmission set that has alot less km's than yours and maybe just maybe they might find u a tweaked out one!!! by tweak i mean already been hi-performinced!!!!!

My CTS 2005 don't not go in reverse but all others gear works

Could either be your shifting linkage needs to be adjusted or your transmission solenoids need to be replaced

Sounds like a cable to the transmission is not adjusted up right, and/or the neutral safety switch is not adjusted right, if this applies to your Toyota Corolla.

Your transmission is bad. You need to replace it soon if you are still driving it. At any moment you may lose forward and only have reverse (trust me it happened to me and I was dumb enough to drive it seven blocks back home in reverse).

Hi:
The shift pattern is pretty much the same on all 5 speed cars. The top row is the odd numbers, 1-3-5
the bottom row is 2-4-Reverse. The center position is neutral

Here is the key: The shifter is slightly spring-loaded to the center position. If you hold in the clutch pedal and pull the shifter to neutral, and let go of it, it will automatically be lined up in the position, that if you pushed it forward , it would go to 3rd gear, and if you pulled it back, it would go into 4th gear.
This way, to start driving, you start out in neutral, grab the shifter lightly, and push it first to the left, then forward. This is first gear, where you start out. when you want to shift to second, push in the clutch, and keeping left pressure on the shifter, pull all the way back . Here is the easy part, 2nd to 3rd. When you are ready, push in the clutch, and just push the gear shift forward , till it hits neutral, and is spring loaded to the middle. Then you just push it straight forward to 3rd, then next shift, straight back to 4th.
Last gear, 5th: push forward to the neutral row, then Push to the right till it lines up ,and forward to the 5th gear. Reverse should only be shifted into from a dead stop. Find neutral, push the shifter all the way right, then pull back towards you. Hope this helps.
Practice a bunch in the driveway!

Check neutral safety switch and security system
