Transmission problem (01 jetta 1.8t)

[@Vertipr0]

I had this problem on my 2004 jetta 1.8T GLS, I swapped out all 9 shift solenoids and drained the old ATF fluid and replaced it with valvoline max life atf fluid. I’ve put around 700 miles on the car since the job and it’s running perfectly now.

[@simplistiksoftware]

Shifts at RPM not speed, speed sensor under trans mount. Slips during change, servo and valve body replace with new ribbon cable. Hard shifting, replace fluid and filter then check pressure and increase till 60-65psi at idle in drive. Reset trans adaptive after every service above. These transmissions are typically good for 300k. More money in replacing then repairing. The entire, Entire, transmission is computer controlled. Hydraulic pressure only applies to drive or reverse clutch. Slipping in all gears, increase pressure. It's just an Allen bolt. Then put the pan back on. You can't reduce pressure without removing valve body. Valve bodies wear from not changing fluid and having abrasive clutch material flowing through them like liquid sandpaper.

[@BryanVoigt]

This is the 1.8T with the 09A trans. All three speed sensors are internal. The trans has to be removed to swap the sensors.

[@imnobody4522]

If you drive hard the adaptive transmission computer remembers your shifting pattern and stretches your shifting points. Do a reset.

[@ianholmen888]

Charles Zimmerman how

[@drulessman3329]

Yeah how do ya reset

[@cta42141]

Limp mode is on. The mk4 vw limp mode makes the car take off in 2nd & only shift to 3rd at or above 4k rpms. You have an issue mechanically that's forcing your car into limp mode, to prevent more damage. Take it to an import mechanic.

[@patatofruit4393]

Happened to me… replaced the output transmission speed sensor located under the transmission mount.. and it fixed it

[@shkumbinhasani3486]

My Jetta TDI has 220,000 miles on it and I recently took it to Chicago and back which was about 750 miles of driving total, the very next day after getting back from my trip, I pulled up to a ref light and noticed the steering got very stiff to the point I couldn't turn the car, then the car Threw itself forward and the engine lost contact and it took me a good 6 or 7 tries to start it back up since it kept saying the battery was dead. So I brought it home and now the car will not switch gears at all, it runs but it won't switch gears

[@adamtaft1062]

Bring it to autozone..have em scan it.. transmission control module can fail if fluid wick up wiring..probably a solenoid though..or like I said fluid low

[@pauliekruger7639]

Have you discovered the trouble yet? Mine won't shift into 4th when it's cold/ warm. There are so many causes its mind boggling. Some say to turn on the key, only, no start, push the fuel pedal a few times and then off, then restart. Some have success.

[@lungalefosa1955]

my jetta also has the same problem, the only difference is that the revers also gets a bit tough to engage when the car has been running for the whole day, but in the morning it engages smoothly. what may be the problem?

[@Pathos312]

Did you ever figure this out? Same situation. 02 1.8t

[@gavyndavis290]

Did u ever figure this out ? Same model and engine

[@akkomaya3924]

what type of speed sensor do I need I learnt that there are many speed sensors on the car

[@furozz7479]

Ekko Maya the sensor is the drive Shaft output sensor. It's locate under the transmition support

[@skullettrump3424]

The problem is that its automatic do a manual swap

[@cookekeon]

I got a 2000 with the VR6 motor & mine does the exact same thing after driving it for a while. so what would the problem be? bad tranny? bad VSS?

[@talk2stars]

thanks, do you guys what the light above the gear on the panel indicates?

[@visionriguy7736]

talk2stars windshield washer fluid

[@evelynoxford7962]

or try changing the transmission control module

[@zipot3chullo]

Is that costly?

[@tristeneast3823]

Definitely not a tcu with a tcu you would’ve completely lost gears my old Honda ended up having only 2&4 but only cost me $80 to fix

[@JustWatchN-j4c]

tristen east Generally I don’t ask for the Koch version but in this case of a $80 fix? You have my attention if you care to elaborate please.

[@CarlosHernandez-wv6hd]

I have the same problem have to change the transmission solenoid the cost me 300 but I have to do by my own

[@cookekeon]

what specifically did you change? transmission speed sensor?

[@nourrialagobey2058]

Which Solenoid did you change sir

[@brianmccray216]

Did you get it fixed and if so where does the plug for that plug into

[@bestfights229]

That’s what happens too mines in 3 gear it kicks in hard

[@adamtaft1062]

Either bad solenoids internally or low fluid level...

[@laytaw777]

I have the same problem what should I do with it?

[@danieloshaughnessy8476]

Here is a link to swapping the valve body. kzbin.info/www/bejne/fX7ZfYtsjpKqjdU

[@mohamednousier6411]

output speed sensor (G68) it is the problem

[@anthonyq123123]

fluid degrade servise trans reset bcm fixed.

[@tyclagon6485]

u had the same problem

[@zipot3chullo]

anthonyq123123 what is the BCM?

[@mahmoudalabdullah6756]

Hello Bro anything new about the problem i have same problem in my VW mk4 Golf

[@mohandabdalah2251]

مرحبا عندي نفس المشكلة وبعد فحص الكمبيوتر تبين انه حساس الجير خربان عندك فكرة عن طريقة تغييره ؟

[@adayinthelifeof6654]

Sounds like speed sensor

[@takmaisim8511]

how did you solve this problem i have too

[@takmaisim8511]

i have a vw bora 1.9 TDI automatic (Jetta mk4) and slip slip slip....

[@erickfacts5463]

transmission Control unit went bad

[@linotellez4116]

Ohhhhh Auuutoos 😏

[@juliotorres512]

Your transmission is in limp mode, and The mechanic shop sucks!!! Check transmission codes because you may have an open circuit in one of your solinoids Wich shifts The gears!! I had a 2001 Jetta vr6 with A 01m transmission And I had the code 00268 that is A #6 shift solinoid open circuit so I replaced the solinoid and The wire harness and also had to replace the transmission control module because the module feed 10amps of current which caused the solinoid to burnout in the first place!!!

[@ceegee3514]

your tranny isnt slipping, its just stuck in certain gear, more than likely your transmission speed sensor. if you continue to drive it in this condition and waiting for the 4,000 rpm range you'll end up damaging the transmission horribly and pretty much end up requiring a new one.

[@zipot3chullo]

Is there a fix in that sensor ? Or just a new tranny?

[@ceegee3514]

Alvaro yovanny Yeah bro your car isn't detecting the correct speed and or rpms to shift correctly . Go online or to junk yards and pull one out , they're not that expensive . Has the issue gotten worse ?

[@zipot3chullo]

sicky gumbo alright man & not actually but i just switch gears manually like if it was a stick & it only goes up to 3rd gear

[@matthewl2813]

Replace shift solenoid

[@alejandrobarberis530]

Its transmission sensor, it happened to me too

[@irvingramirezgonzalez3602]

The transmision sensor is the TCM?

[@staudtc91]

Which one?

[@mohandabdalah2251]

Give me a solution how I can replace the sensor

[@khadijahross7184]

Hey I'm having the same problem with my car. Did you ever get yours fixed?

[@zipot3chullo]

+Khadijah Ross well, my only solution was getting a new vehicle since it's a german car and it's costly to even take it to a german dealer to see what is wrong

[@yourgirlraex3]

+AL Shovanni did you end up selling or keeping it?

[@zipot3chullo]

Selling it that's the only option, if I didn't sell it I would still be having other problems with it

[@mahmoudalabdullah6756]

Anything new about the problem i have same problem

[@salascook]

Young AL

[@danlebrun1487]

Its a vw jetta

[@MyTigre77]

Try the junkyard first

[@zipot3chullo]

Lol good idea but not when you need a car and dont have money to get a new one

[@tbckiller4]

"4000 revolutions" sorry but that was funny xD

[@evelynoxford7962]

your transmission is slipping badly you will need a rebuild or a new one

[@erinrichardson5936]

you obviously know little about transmissions or VWs and probably best not to make uneducated comments regarding repairs
