Limp Mode, P0722 OBD code, and Vehicle Speed Sensor

[Jessica44]

I have a 96 Vw Jetta. I'm having problems with 4th gear. It shifts a little hard from 1st to 2nd, fine into 3rd, and will go into 4th. As soon as pressure is applied to the gas pedal to speed up, it slips out of 4th gear, (kinda like it won't downshift to 3rd). If you let off the gas pedal it will catch 4th again, but again if you apply any pressure to the pedal it will slip right back out. It used to be an intermittent problem but lately it does it all the time. Changed the wire harness, solenoid, TCM, and the plastic plugs in the valve body. When I recently replaced the TCM it seemed fine, but we had to drop the pan and fix a leak in the pan and ever since then the 4th gear issue has been an everyday occurance. We've tried scanning for codes, but haven't come up with anything on the tranny. It is NOT in limp mode. I'm on the verge of just taking a baseball bat to the car. Any help would be greatly appreciated.

Re: My cars shifting again
Well for anyone who sees this, since i ran the car with the transmission sensor unplugged it put it in limp mode on my 99.5 MKIV Jetta 2.0 auto. I had a friend at a transmission shop scan it with a European scanner and it had a bunch of codes for the transmision sensors stored. "it had several others because i unplugged a bunch of crap looking for a short" After he cleared them, all is well, Jetta is out of limp mode and driving fine. Shifts smoother than before. So before you go to the dealer with "limp mode" try to find a 'friend' with a vag-com or european scanner. A lot of smaller shops even have them. At a shop it was going to be $80, but if you know someone inside, they may help for a much lower price. just throw them a bone please.
Thanks for this thread, wudn't have known wat to do if it wudn't for this thread. I disconnected my connectors on top of the transmission trying to find a short ( drove it a mile with one unplugged) and threw it into 'limp mode' after that i did this fix above it fixed it and the only code that came back was the MAF sensor and I can fix that.

Thanks for the info. I used this thread to diagnose my 97 Eurovan camper with an identical problem. I replaced the G68 sensor. It is very accessible on this vehicle. remove the skid plate from the bottom and this sensor is located on the front side of the transmission, two wires, maybe a foot to the side of the driver side front tire. On the oppposite (rear side) of the transmission is the Multi Function switch with about 6 wires coming out of it. I just jacked up the drivers side a bit, crawled under and swapped it out with a speed sensor (part# 13-0112) I got from O'reilley auto parts. Works great now. Hope this helps someone else.

I have a 2000 VW Golf Gls 1.8t AWD Automatic. a couple months ago the timing gear on the cam broke and really did a number on the motor so I rebuilt the whole thing all new Bearings, oil pump, new AEB cylinder head and turbo, car runs great! No problem with motor but I do have one code P0722 (Output Speed Sensor) Now I am having a hard time trying to trying to decide which speed sensor to change. Any ideas on what I might try first? I can't decide to get the g36 or g68

722 relates to the G68 sensor.

Im getting so frustrated with my jetta I want to burn it to the ground!

So iv been messing with cars my whole life and this is the first time iv been stumped lol, my previous cars gave me the same problems and I fixed them no issue until now.

It started giving me problems like massive amount of vibration not picking up speed on full throttle and when i'm going over 100 the speed is not accurate and just stays at 100(iv checked with my gps, it says 100 but was really at 140) but I know how to control it by rpm so im good there but will fix that either way and a weird smell, she does this when ever she wants to and it pisses me off.

I'm in Canada and I would like to know where I can get these sensors, im done with this problem its so bad I just want to sell it and finish my civic.

The latest problem it gave me was that it didn't want to change gear, at all.

I gave her a full tune up, cleared all the codes and it was quite strong but then boom pops right back into limp mode.

I bought it as an engagement gift for my fiancée and regret it so bad.

I was even planning on modding it for her, already have some nice wheels for it, if it isn't solved soon she will be dismissed.

Please help me out.
