I put my trans. into reverse and it screamed than made a sound like a bucket of bults and now I have to shift my forward gears manually. Reverse quit. What happened?

Remove trans pan and check your manual valve it may be broken, or linkage problem, if no problem found then you will need to take a pressure reading but that may be out of your capabilities, have a shop check your trans and give you a diagnostic.

Sounds like an internal problem with the transmission which will take a shop to repair.

The clutch is not clearing properly ,so wait a while for it to level itself off ,to get reverse in the meantime you stop engine ,put in reverse then start engine ,if after a while it still doesnt work and tries to jump out of gear you will have to strip the gearbox and change the dog gear

The question is a little vague but I think I know what your referring to. All modern automatic transmissions have torque converters. This is the device that connects the engine to the transmission. All vehicle manufacturers like the trans to be nice and smooth shifting. That's great but it does come with some minor drawbacks. If you are facing slightly down hill and you put your car in reverse but do not step on the gas slightly I can guarantee that you will indeed roll forward. You can eliminate that issue by holding your left foot on the brake while you shift into reverse. Then, as soon as you feel the trans engage, gently depress the gas pedal with your right foot and it will eliminate that forward roll problem.

not sure if this is an automatic or manual transmission 1st (automatic)if all forward gears are still working what it sounds like is that the reverse drum in the transmission has come apart. which will eventually cause the forward gears to start to go if thats the case, the rapir for the reverse drum is internal the transmission will need to be rebuilt. you can just put a reverse drum, but my opinion is there will be more damage and while its out might as well rebuild the entire transmission. you didnt mention if it was 4 wd or not and only rarely have i seen a transfer case cause the same issue, once most recently in a f150 with a manual transmission i was working on the chain stretched so bad it lost reverse but had all forward gears. 2nd (manual) could have lost the reverse synchronizer whic again the trans will need to be repaired either with just a syncro or complete rebuild. hope this helps

Hello. As you know, the transmission is one of the more sophisticated components in any auto. It takes the most transmission pressure to engage reverse, third, and fourth gear in an auto tranny. In an auto tranny, the shifter is connected to a linkage that manually shifts between the different gears in the transmission. When you shift into reverse, all transmission pressure is concentrated to engage reverse. When you shift to drive the transmission will operate normally, building pressure until it can shift into the next gear. With third, second, or first gear selected it will lock out all higher gears (Unless the TCU detects overrevving of the engine, in which case it will override gear selection and upshift to avoid engine damage). All the TCU does in a modern auto tranny is control shift points. Years and years ago, shifting was controlled by a spring attached to the gas pedal. When the gas pedal was depressed, the spring would expand. As tranny pressure grew, the spring would become compressed until it was fully compressed, engaging the next gear. The harder you stepped on the gas, the longer you went until the tranny shifted. In modern transmissions the TCU dictates shift points, and not much else. The TCU will also control when the torque converter will lock, but that's where it's duties end. The problem with engaging reverse is either a linkage issue, or a problem with the pump not building enough pressure to fully engage reverse.

Try putting the shifter in reverse, holding the brakes firmly, and giving the car gas. If the car reaches a higher RPM and suddenly slams into reverse it is the pump. The pump will only build enough pressure to engage reverse with higher RPM's. If the pump is severly damaged it won't engage at all, but if this is the case it probably won't engage third or fourth gear either at that point. If the problem is with the linkage, reverse just won't engage whatsoever, despite RPM's. I'd say start with the shift linkage. If it's bent or misadjusted it could cause reverse to not be fully engaged. The TCU doesn't control reverse at all, since there are no shift points and no need for the torque converter to lock.

If I understand you correctly, you have ALL forward gears working, but reverse doesn't?... then the problem is in the transmission itself or the linkage on the trans linkage into reverse.

There isn't a modulator on this trans as it is electronic

You can have first gear going forwrd but no reverse. It is possible. The low/ reverse clutch isn't needed to go forward.

YOU HAVE A SHIFT SOLENOID THAT HAS EITHER FAILED OR IS STUCK, DO YOU HAVE ANY TRANS TROUBLE CODES?

If the vehcile is V6,then the trans model is the A540E,and if it is the 4 cylinder engine,the trans model is an A140E.Both are 4 speed overdrive transmissions,and sorry to report that on just abot every automatic trans on the road,reverse gear failure is almost always a mechanical problem inside the transmission because there are no shift solenoids involved with reverse as with forward gears.And you did say the forward gears were fine.Good luck.
