Quite a common problem with ZF-6HP auto gearbox. This is the infamous "gear slam". Had it on my e60 and resolved with replacement of the 7 mechatronics solenoids.

is the number 6 in the picture?

Lee,

Please click here for more images of ZF-6HP19 auto gearbox. https://www.google.com.my/search?q=...UHsvhrAem0oGQDg&ved=0CEEQsAQ&biw=1366&bih=499. The 3rd image is the megatronics (valve body) and the 7 pieces of solenoids (yellow, black & blue) are located on the right side of the megatronics.

Just google for more information on ZF-6HP19.

You should return to the workshop and ask them to check. After replacement of new solenoids, workshop need to reset the values of the solenoids, go for test drive and then reset the values again. By the way, are the solenoids new and original from ZF ?

I did mine with Mscope. Rebuild the mechatronic and changed all solenoids. It need to be reprogrammed and took me three times to get it right. Software update also can resolve the gear slam issue. You may try both.

My e90 325i 2006 had the same prob... would try the software update first.. which is the best place to do the update? and roughly cost how much?

many thanks...

 

[kolamp]

Done the software update but jerking when downshift to gear 1 still exist....well i guess the solenoid need to be change as well...

 

[Herbert]

No point spending RM450 to update ECU/Auto Trans software. Rectify the gearbox jerk problem first. Then only do the software updates.

Hi Herbert, any recommended workshop to change the solenoid? and the cost like?

Thank you.

Dear Herbert

change of Solenoids or change of the whole mechatronics?

i was quoted about 5k+ to change the mechatronics.

Which workshop you went to?

 

[wingzee]

How about jerks when upshifts, esp 1st to 2nd? Anyone experienced with 6HP19?

 

[FIRZ67]

Hi wingzee, both situations are cause by solenoids in the mechatronic module. My first car experience the jerk when upshift, later it went to the downshift issues. Rebuild my mechatronic at Mscope Batu caves and problem solved. But after the rebuild I need to go through 2times of gear adaptive value reset and reprogramming to fine tune the setting.

FIRZ67,

Thanks for sharing with us your experience with Mscope. A couple of clarifications if you won't mind.

1. were the solenoids at mechatronics replaced with new ones?
2. rebuild your mechatronics. Did they actually opened up the mechatronics?

 

[FIRZ67]

As they claimed they changed to a new one. They need to open the mechatronic module to change the solenoids.

As they claimed they changed to a new one. They need to open the mechatronic module to change the solenoids.

Thanks for clarifications. To replace the solenoids, they need to removed the mechatronics module from the auto gearbox as the solenoids are attached to the side of the mechatronics module. I don't think your mechatronics module was ever opened up and rebuilt (overhauled).

Thanks for sharing, mate. Mine only clocks 40k km so far and yet to undergo first ATF change. Gonna try that first and see how it goes. Solenoids starting to fail at such milleage is just beyond me.

any place to recommend for change of mechatronics?
