when I'm in first gear at 4000-5000 rpms it doesn't let me shift to second or put it into neutral. I also can't put it into reverse unless the car is not running and then turn it on to reverse it. Is it CAGS or something else?

 

sounds to me like your clutch fluid could be seriously dirty. did you check it? it might be too late...

 

I was doing some reading on here and they say after 2200rpms CAGS is diabled, not sure though. Also a search said this about reverse:

just went through some issues myself....Ill tell you this- The skip shift solenoid and the reverse lockout can be clipped into each other. And if you have one of those skip shift eliminators, like i do, the solenoid on the side of the tranny(the skip shift solenoid itself) doesn t get anything plugged into it cause the pigtail(wire connector) has a plastic looking thing plugged into it already. So the one on the side of the tranny in the pic Byron sent u is the skip shift solenoid. If you re not getting it into reverse, ill bet $1.00 its the solenoid on the top either isn t plugged in or it is plugged into the wrong solenoid(skip sh solenoid). Prob not the adjustment. I learned this after Byron sent me the same pic and i laid under my car for an hour or two looking for another wire connector, only to realize that there wasn t one, i had the reverse lockout connector clipped into the skip shift solenoid. So i unplugged the connector out of the solenoid and plugged it into the reverse lockout solenoid and- WALLA!!! Reverse!! I hope this helps you, if you don t already have it figured out!! Remember, if u have the bypass for the skip shift, you will leave the solenoid unhooked from the wire connector because you ll have a plastic looking thing plugged into the wire connector that origionally plugged up there. Good Luck!!-Jason

Not sure if any off this will help; I'm sure someone on here knows, but they may need more info or trouble shooting on your part.

 

Find the problem yet??

 

no i haven't, completely don't have any idea. Well some of my mechanic friends think its the synchros (not sure how to spell that...lol) because the gate by 5th doesn't let it slide into reverse unless the cars off or you have to play with it while the cars running by shifting into diff gears and then trying to slide it into reverse sometimes it works

 

You seem to have a few issues going on. All manual transmission equipped C5's have a reverse lock out switch located on the top rear of the transmission case. It will not let you shift into reverse if you're going more than 3 mph.

Your other shifting problems could be caused by a number of issues.

I would start with a shifter alignment and changing the transmission fluid.

If that doesn't correct the situation, more than likely it's your synchro's or blocker rings are shot.
