ZF transmission kit installed - now shifts appalling - Page 3

I'm torn between doing another full reset of adaptions on the highway and doing the 9 run procedure or leaving it and seeing if it improves.

So an update,

Shifts continuing to improve by themselves, the downshift from 2nd to 1st still needs work but also not as bad.

Good to hear! I hope the 2-1 works itself out. For me, with only 47.5k miles, I probably didn't need to do the solenoids, but it was easy enough to do while the valve body was out.

Thanks Haigha.

In Australia the solenoid kit is pretty expensive at around $900 so hopefully I don't need it.

I've got around 210,000 km on mine.

If I thought about it I probably should have at least pulled them all out and cleaned the screens on them.

Oh well.

You can replace just one solenoid if you can confirm just that one failed.

I was ready to do that on mine before i found out the electrical plug was filled with rusty water.

Was a different model transmission, and with no transmission splash shield like our diesels....

Ahhh ok.

Shifts great everywhere now apart from when warm coming to a stop and going 2nd 1st. It's not there when cold, only after it's warm and in city traffic which is annoying as I'm right in the city and average about 15-20mph usually so lots of start stop traffic.

I still haven't done another reset and followed the procedure on the FCPeuro site.

Edit: manually shifting is fine. No idea why it comes practically to a stop in 2nd then jolts itself into first. If I brake harder no problem, only when gently rolling to a stop.

I (currently) have the same thing. Many of us do...

I've heard that new fluid (esp. MaxLife) can sort this. I've also heard of folk that have changed the fluid to sort this and had no change. You and I included...

I've heard that changing the bridge and jump seals can sort this. I've also heard of folk that have changed the bridge and jump seals to sort this and had no change. You and I included...

I've heard that resetting the adaptations can sort this. I've also heard of folk that have reset the adaptations to sort this and had no change. You and I included...

I've heard that new solenoids can sort this. I've also heard of folk that have changed the solenoids to sort this and had no change.

I've heard that an EGS re-flash can sort this. I've also heard of folk that have done an EGS re-flash to sort this and had no change.

You get the idea...
