OK, I've pulled the mechatronic unit from the transmission, replaced the 7 solenoids and am trying to refit it. I am struggling with engaging the new wiring harness sleeve to the electrical connector's locking tab on the mechatronic - it won't close. It seems a metal spring plate stops it closing.
Any advice on how to reinstall this part?

 

So did you get it working - sorry I cannot help with any advice

 

There is a vertical tab inside the sleeve that needs to be between 5 and six o’clock position.

Push sleeve all the way until seated then push up locking tab. if you have tried to lock tab without the sleeve fully seated the tab end could be bent.

Good luck

 

Yes, thanks to all for the advice. I disassembled it all again, worked out how the locking mechanism worked then reassembled. The transmission shifts properly and does not slip any more. Saved the cars life, as it is not worth enough to justify a new transmission.

 

where did you buy the new solenoids, and can you remove them while it is still in the transmition or do you have to pull the valve body out to replace them

 

I bought them online from https://www.thectsc.com/ but there are many suppliers available. You do need to pull the valve body out, but it is pretty straightforward and only takes about 10 mins.

 

Gotcha, is there a gasket that needs replaced for the valve body

 

You will need the following:
solenoids
connector sleeve
pan gasket
upgraded transmission pan with separate transmission filter (remove old pan by cutting plastic neck off the old integrated filter, no need to remove exhaust, cross-member or raise the engine)
Lifeguard 6 fluid
Fluid pump.
Cost me around $600 and maybe 4 hours all up, which is less than most places would charge you for a transmission fluid and filter change.

 

Awesome, i appreciate the info

 

Well it was about 6ish hours today but it is done and it shifts like a dream

- i drained the oil
- removed the pan
- removed the valve body
- replaced the solenoids which through me for a loop the old ones were yellow, green, and one black, the new ones are yellow, blue and one black so i found a YouTube guy that workes on these transmisions and his new ones are blue so i put them in
- installed the valve body
- installed the sleeve
- installed the filter and pan
- filled her up
- road test and super stoked how it is shifting

again i appreciate all the info

it was a pain in the neck only having the vehicle on jack stands but still worth it
