With no information and no way to diagnose this and since a shop did look at the car then I would have to assume its been diagnosed and the computer is at fault. If the trans still works then solenoids or computer is the only other choices.

Best bet is to follow their advise or go get a second diagnoses some where else to confirm it.

I have a 98 land rovor will not go in to gear ?


it won\'t go into gear as in the shifter does not come out of "park"? or vehicle will not move when placed in "reverse" or "drive"? if its not coming out of "park" you may either have a faulty brake switch or shifter lock solenoid is stuck. on certain european automobiles i have come across the shifter stays locked because the internal solenoid in the shifter assembly has gone bad and the entire shifter ass\'y would need to be replaced. this is the worst case scenario. majority of the time its a bad brake light switch not sending the signal to the shift interlock to release the solenoid within the shifter.

now if your vehicle is failing to move while in "reverse" or "drive" you have some sort of internal failure with the trans. it can be something as simple as a shift solenoid or major such as broken planetary gear.

Is there gearlinkage upgrades for gearshift problems on the manual transmissin ,internally ?


The issue almost has to be external. There is only one shift rod on these cars; it rotate a set amount and goes in-an-out. These shifters have a ball bushing at tunnel and attach to an arm that ties them to the transmission. There are several bushings/bolts/pins in this mechanism that are prone to failure. Unless you have had this car on a rack and dropped the transmission down, I am fairly confident that you have not changed all of the bushings. Also, failure of the transmission mount itself could allow for movement of the shifter (actually the transmission is moving appearing to move the shifter). This was a common failure on the M3 that caused many blown engines during down shifting resulting in grabbing 2nd instead of 4th and over-revving the engine.

Hope this helps,

2003 ford transit turbo manual gearbox, stuck in 2nd gear, cant start


does the clutch push normally or is the linkage broken not disengaging clutch, and then does shifter move around or locked and wont move, loose linkage in shifter or gears are jammed inside transmission and something went, if shifter wont move at all then trans is jammed inside and needs repair.

What is O/D on 1995 Toyota Camry? Light says O/D Off and car won't go into any forward gear. It runs and will back up, but not go forward.


o/d stands for over drive which is 4th gear in that trans.there is a button on the shifter to disable that gear for bad road conditions.depress the button to change,car should mostly be driven with o/d selected,meaning press the button until the o/d off light goes out.with all that said,if the light display wont go out it could indicate a trans failure code is present.if your car wont move in any forward gears,most likely you have in internal trans failure.check trans fluid level and condition,full and red is good.brown or darker colored fluid is bad.if fluid is low,then add to full mark and inspect for leaks.

My problem is that the manual transmission is stuck in 4th gear. I was backing up when I went to put it into 1st the shifter was stuck. The clutch works to disengage the gears but the shifter won't...


That cylinder is known as the clutch slave cylinder. It should push against the clutch fork every time the clutch pedal is depressed to allow gear changes. If it doesn't, suspect a faulty slave cylinder, or clutch master cylinder.

My gear shifter won't move out of park on my 2006

This problem also happened to me. However, I found the part online that replaces the second pink lever. The new part is made of metal so the part will never break again. I made the emergency fix with the dremel, ordered the part, and a week later the part came. I am making the permanent fix today. Follow the link above to order the new part. It costs around 49.00 including tax and shipping. It will take you appx 2 hours to remove the shifter, change the part, and reinstall.

I have a 79 chevy bonanza c 10. The truck will not engage in any gears. The shifter will be in the position but nothing happens when i hit hte gas. Its an automatic transmission. What could the problem be?


The first thing to do is check the trans fluid level and make sure it's full,engine running and truck in park. If it's low top it up and manually shift it slowly through the all the gears. Check the fluid again and top up if necessary. If this cures it you need to be checking for leaks.
If it's full, crawl under the truck and check to make sure the linkage is still hooked together. The shifter linkage could get knocked out of the transmission, it's just a spring loaded fit. With the truck turned off and the wheels blocked so it won't roll, have someone move the shifter through the gears. Watch to see if the shift mechanism on the side of the tranny moves with the shifter. If it doesn't you will have to find where it came apart and fix that.
If this all checks out then it's probable that the trans in going to have to come out and be repaired or replaced because the problem is internal. If it has been slowly getting worse, more gas pedal to keep the same speed or to get it moving, the clutchs are likely worn out. If it happened all of a sudden, it's likely that the pump has gone bad. Either means tearing it apart. You could try taking the pan off of it and checking to see if the filter is plugged. Changing it and the fluid may fix it if the filter is plugged. If you do this, add a bottle of Lucas transmission additive and you may buy yourself some time but a plugged filter and no go means you should start shopping for another transmission. It's just a matter of time before it goes for good. Hope this helps.
