Q:i have a 1994 volkswagen jetta 3 GL an im tryin to locate the transmission vaccum hoses becuse my transmission isnt changein gears an we think it might be a vaccum hose but it shift like if us manualy shift it like going through the low range gears

They used to use a vacuum hose to a round diaphram modulator near the bottom of the transmission, just above the oilpan. I thought they had changed, first to a bowden cable, then to electronics. So I doubt they use a vacuum modulator any more. When they did, it was checked by removing the hose to see if there was any ATF in it. If there was, then it had to have a cracked diaphram. First start by checking the fluid level. If the transmission fluid level is low be sure to check your transmission for a transmission fluid leak. A leaking transmission is usually caused by a bad seal, gasket, o ring or transmission cooler line. If the fluid is dark or smells burned, it is time for a rebuild. But if low, then that may be all it requires. Make sure you check with engine running. Second have your vehicle scanned for computer diagnostic trouble codes. These codes help determine what component or circuits are failing. Now a transmission with a shift control problem can be due to an electronic computer control component or part. Computer control problems are usually due to a bad sensor, circuit wiring or computer itself. Some transmission problems can be caused by a bad transmission temperature or speed sensor. Transmission shift control problems can also be caused by a bad engine load sensor such as bad throttle position sensor. A slipping transmission can be due to the transmission losing internal oil pressure. Oil pressure is lost when internal sealing rings or seals fail to seal the clutch drum piston circuits. Although some manufacturers specify that their transmission fluids are for a lifetime, you should consider changing it out every 50k miles. So be sure to service your transmission to help prolong the life of your transmission.

Q:How can i fined out what year transmission i have when it is already out of the vehicle?

Every transmission has a serial number on the side of it, when decoded it tells you all the information! I would Google the code to figure it out, good luck!

Q:I‘ve got one of these brand new 2014 Nissan Sedans (at 1k miles so far) and am a little concerned with what I‘m seeing online.I‘m a bit of a skeptic and all I‘m see is anecdotal, more negative things about CVT than positive.And I get the feeling that people don‘t say anything until something goes wrong so these anecdotes aren‘t representative of the overall reliability of CVT‘sSo is there anything more scientific out there that takes a look at the reliability of CVT‘s?Any studies or mechanics/experts that may be able to tell what the failure rate of CVT‘s is in comparison to other transmissions?Thanks

I don't know if any of my experience carries-over to the Nissan . . . have a Ford Five Hundred CVT AWD. We like it - but heard the same reliability horror stories and have talked to many mechanics, the dealer service dept, and done some online research. The Ford CVT is no less reliable than their other auto transmissions - - but is unforgiving of lapsed maintenance. Our other Ford with a conventional automatic doesn't need service until 100,000 miles, but the CVT is to be serviced at 60,000 - - - reason: the anti-wear additives in the special fluid wearout and there would be excessive wear to drive chains. Every quick oil change shop we asked was ready to flush the transmission for us . . . although they were unaware of the special CVT fluid required, or that it has two filters that MUST be changed. If you skip service and the transmission fails prematurely, dealers don't fool around trying to repair it - - - they replace it and costs of $5000+ are not uncommon. We had ours PROPERLY serviced on time and continue to have no problems. As we expected the car gets about 1 mpg less than the conventional automatic, but that is probably from the full-time AWD. The transmission is a wonder: smooth, always INSTANTLY in the correct ratio (we have a steep, steep driveway and must manually downshift other cars - but not the CVT). We are disappointed that Ford no longer offers the CVT in the new Taurus . . . . which is why Nissan is on our list for next car - so we can have another CVT. ADDED Monkeysnot: There may have been others, but Dutch manufacturer DAF introduced Variomatic transmission in 1958. . . the patents for which were one of the reasons Volvo later bought DAF . . . and Ford bought Volvo !

Q:i have a 1970 pontaic le mans.i put in a 350 oldsmobile transmission but my crossmember is not long enough. what can i do?

Sounds like you installed a Long tail shaft transmission in your car. Most likely out of a bigger car or wagon.After removing a short tail shaft trans. We need to know if you pulled out a Manual transmisson or a Turbo 400 or TH350 . Most likely you need a A body only transnission to replace yours. Take it back, if its a used one, its the wrong one, Pontiac, Olds or Buick will work but needs to be Short tail shaft. Or You need to have the tail shaft replaced with one like on your old transmission. Might can have your swapped over? Tail shaft is the last part of the transmission housing. Modifying your crossmember and having a new driveshaft made not smart just incase the transmission might not be very good or last more than a year.

Q:Hey everyone,My 02 Jetta has no reverse at the moment, and the mechanic says something came loose in the back of the transmission. However, he scanned for codes and found a Catalytic converter below bank threshold message which states that the converter is causing the fluids in the transmission to overheat.Since the catalytic converter has a 10-year warranty, could I have a case with making VW pay for the transmission services?After all, the converter did cause this!Thoughts?

the catalytic converter in no way related to the transmission. it's just coincidence that you have a code for it at the same time. there is no way you will be able to get VW to warranty transmission work for a bad cat.

Q:My 1993 Nissan Altima started leaking a lot of transmission fluid. Prior to this the car was running fine. Any ideas what is wrong?

FOR SURE!! take the bike back. have a little talk with the salesman who sold u this bike. demand your money back, ask for the owner and let him know u will be writing an e-mail to the head office. when u write the e-mail, be professional yet firm on your, disappointing, purchase and experience with the company.

Q:When I try to put my van in drive it wont move sounds like it is stuck in neutral. Dose this mean I will need a new transmission?

It is the transmission, check fluids and run through all the gears to see if none respond. You should give the make and model it helps because some vehicles have certain problems associated with them

Q:Hey everyone, I have a 1994 Firebird Fomula. It has the 5.7 motor with the 4L60E Transmission. Whenever I punch the gas, as I‘m driving down the road, the transmission just slips and wont shift , so I have to let off the gas , so the motor doesn‘t red line. As I drive around town normally , transmission shifts just fine and you cant even tell there is a problem. I suspect its something to do with the overdrive, since if I run with the trans in 3rd and punch the gas, the trans doesnt slip like it normally would if I flored it. Any Ideas whats going on??? Please Help!

The transmission is past its prime. It is wearing out. You could have the bands adjusted and get some more time out of it, but the new Formula is, drive like a little old lady. Shop for a rebuilt transmission while you still can drive.

Q:the transmission is a 2-speed GM ST300 (super turbine)

Hey Weird, If your asking us on Yahoo. You have no idea what you are doin. How do you know it needs to be adjusted. One of your buddies say that. A 2-speed is not a hot rod piece of equipment. It is for the family sedan. Leave it alone before you break it and then you will be out of luck for a vehicle. Take it to the experts at the tranny shop for servicing and reality check. You want to be a mechanic--go to school. How do you think they learned??

Q:I have a 94 Acura Legend. The transmissions slipping gears (worst is 1st to 2nd). Is there something that I can do to help it? I found out that my transmission fluid is down to about 1/2. Can that be my problem? Is there something I can do to not have to buy a new one? PLEASE HELP! Can someone tell me further about what I can do to at least help it? Iv been going real easy on it. THX!

I also own a 94 Acura Legend. Unfortunately our Legends were built with a weak transmission. They are notorious for transmission failure. Here is what you need to do to prevent an expensive rebuild if it's not too late. Buy some cheap transmission fluid to put into your transmission. You'll need about 8 quarts(or just make sure there is enough. Make sure fluid is between the indicator marker on you dipstick while the engine is warm) . This is just to see if your transmission still works. It should shift better if your lucky. If not, then its time to get your transmission rebuilt. If you notice a dramatically smother increase in shifting, then you are lucky. Then you can do a real transmission flush with high quality OEM Acura transmission fluid. You need to get 10 quarts of OEM Acura Transmission fluid from the dealer. (10qts 8$) Do a complete flush by finding the transmission cooler line, removing it, turning your key to on, remove one quart from the cooler line, add one quart from the top, and repeat. GOOD LUCK!!!!!! I love my Legend, please let me know if you have any more questions.
