Why would a car slip out of gear?

Answer 1

Your vehicle could simply need a clutch adjustment.

i have a 83 Toyota Camry and it slips out of gear and i have been told that it is the syncro that is gone and that is why it slips out of gear but for the cost of fixing this id rather go with the clutch adjustment

I have to say I have many years experience in standard transmission. I have had those problems with the transmission popping out of gear. In my case it was the first gear tooth was broken. This surely is more a sensable answer. The sycros, is what allows you go in and out of gear without clutching. The adjustment of clutch is only going to allow you shift gears.

how do you know he or she is talking about a standard transmission what kind of trans is it automatic is it standard?if its an auto its just very possible it needs some fliud,hense you would have a leak,INFO INFO INFO NEEDED.i would think that this answer asking for more info would be the more sensible answer

OK, first off the individual is more than likely asking about a manual transmission because they mention "clutch adjustment" which occurs only with a manual transmission. An automatic transmission has clutch packs and bands with friction material on them that tighten or loosen around a drum inside the transmission..among other things. It is safe to assume it's a manual transmission as the vast majority of people would not know about clutch packs in an automatic. At least ones searching on wiki-whatever..

Second, the synchronizers in a manual transmission aren't for allowing you to shift without using the clutch, that is called rev-matching and when you do that you are actually doing what the synchronizers are designed to do in the first place. They have friction material around the inner side and when you move the gear shift you are moving forks connected to syncros in the transmission. The syncro uses the friction material to more or less slow down or speed up its rotation to match the gear and teeth you are about to match it to (to whatever the engine speed is). When you rev-match you match the engine rpm to that of the syncro. The use of the clutch takes the pressure off of the teeth that are mated or about to be mated allowing you to change gears. If you can match the rpms there won't be pressure on the teeth until you put the car under load by accelerating once in gear again.

As long as the car does not grind, the linkage is most likely fine and any adjustment will probably have no affect. Unless it's adjusted too short to the point you never actually get the car in gear completely.. if it hasn't been tampered with then your problem more than very likely lies with the synchronizers in your transmission. If the car has been put under much distress the teeth on the actual drive gears themselves may be worn to the point they "pop out". You may not know the complete damage until it's taken a part. My 2-cents.

ANSWER

Jumping out of gear in a manual transmission is useually a sign of a worn detent in the internal shift linkage under the shift cover. The purpose of a syncro is to allow for a clash free shift into gear. Syncros do not hold a gear selection in gear. Worn external shift linkage that does not allow enough travel to trip the detent will also cause this, like in the old collum shift 3 speeds. Worn linkage is more often than not the root of the problem. If this an Automatic trans the list of causes is HUGE. If it is automatic prepair yourself for a trip to the credit union and the transmission shop because it's most likely worn clutches and clutch drum seals. RE: Expensive work! Seldom is it something as simple as a pump or a converter.
