JF506E Valve Body

The JF506E is manufactured by the Jatco company (Japanese Automatic Transmission Company) which produces automatic and CVT transmissions. Originally owned by Nissan and Mazda, Jatco is now an independent company and supplies transmissions to most major automobile companies.

The Jaguar and Volkswagen valve bodies look identical except that the VW valve body has the VW logo cast into it. Of the nine solenoids used in this valve body only 4 have double o-rings on the Jaguar and VW. Mazda has 7 double o-rings solenoids.

We offer premium remanufactured / rebuilt valve bodies. All the EPC solenoids are new and the shift solenoids are tested. The one pictured in this posting is the Volkswagen valve body remaned and tested.

Here is a list of some of the vehicles that use the JF506-E:

VW Golf (09A)
VW GTI
VW Sharan
VW Jetta
Land Rover Freelander
Jaguar X-Type
Ford Mondeo
Ford Galaxy (MPV)
Mazda 6 (5F31J / JA5A-EL)
Mazda MPV (RE5F01A)
Rover 75
Seat Altea
Seat Alhambra

I want to change my valve block and I can find quiclier a mazda one to fit my VW 2001 Jetta with (09a)

The valve bodies for the Mazda and Volkswagen are different. We offer this valve body new oem and re-manufactured with updates when available.

The solenoids are the same, as of the date of this comment, for all VW solenoids and for all Mazda solenoids (they are different sets for the two; see blog for more info).

As far as the actual valve bodies go we offer one for the Jaguar / Land Rover, one for Mazda, and one for VW; each having their on distinctive part number.

Hi John, thank you for all your help with my Jetta. You saved me a bunch of money. The dealer wanted me to replace the whole unit. The solenoid kit and the wire harness did the trick and my car is working fine. I will definitely tell everyone about you.

I am glad everything worked out well Dale. Thank you for the kind words.

Hello

I have problems with my 2003 TDCI Ford Mondeo. When we start it from cold and attempt to put it in gear it will stall, it will also periodically do this when pulling up at junctions as well.

Any advice?

Many thanks

Ian

Hello,

For what it sounds like it seems to be a solenoid problem.

Hi bo,

The first thing I would do is check the solenoids. The JF506E for the VW and other vehicles using this transmission experiences issues with the solenoids that sound just like the your vehicle is having.

Thanks for explaining about this Japanese Transmission valve body with the diagrams. It really helped me lot.

@Mark You are very welcome.

I have a 2005 mk4 jetta GLI with the 09a that's not wanting to shift from 3rd to 4th especially when it's cold. Once it warms up it shifts ok-ish unless the air temp is cold like now in the winter time. It has a delay from 3rd to 4th and it will either rev and then go into 4th or downshift all the way back to 1st. VW dealership says I need a new transmission. I changed the fluid and there was no metal shavings or metal bits in it. Do I need a transmission or would a valve body with new solenoids fix this?

Hello Seth,

It sounds like a solenoid issue to me. There is a possibility you will need the valve body. I would scan the vehicle first. The part number 98420 (solenoid kit) comes with a free pan gasket.

hi,
i have a Golf 4 1.9TDi with 09A 321 105 automatic transmission 5 gears.
The prob is ,when i drive the car (hot or cool) kick out gears(in D mode).
thnx in advance

Hello ΡΑΔΙΟ ΠΕΝΤΑΛΟΦΟΣ,

It sounds like a problem with the solenoids or the the valve body. I would take the vehicle and have it scanned first to see if any codes come up. Let us know. John.

Hi There! My 2003 VW GOLF GTI 09A tranny wont shift to 3rd when cold (from 2st directly to 4th). All other gears normal. When warmed up it shifts to 3rd but harsh shift. Solenoids or something else?
When cold and driving it throws p0733. Frustrated :(

Hello generalfkj,

It sounds like the solenoid. When the transmission is cold the fluid viscous and a damaged solenoid has trouble working correctly. Once it warms up the solenoid works with less trouble.

So we have the notorious JF506E and suspect from reading these comments that we have a solenoid issue. We ended up unplugging all 9 but need to know how to test them. Should all 9 click when power is applied? Some do some dont.

(sorry if this is a double post. Was having trouble with my Android getting the robot test to work)

The ideal way to test them would be in the transmission with fluid and a scanner. It would be better to test the ohms. Some might click and some might not. I've heard from different clients the same solenoid clicking and not clicking and the ohms reading to be the same. Its been our experience the best solution is to replace the solenoids and check the harness too.
