Launching "Operation Fix the Transmission" ... SUCCESS!!

[X5only]

I've set out to fix my X5 transmission 6HP-26X. Mileage 167,767 miles, never before been serviced in any way.

Symptoms but no error codes:

1) Low fluid (trans perfectly level with leveler placed on its center) and not a drop of oil when engine running and trans oil temp at 38C (via ISTA). I was shocked to find the oil fill plug could be opened by hand!

2) Occasional "kick from behind". Confirmed the EGS module has the latest firmware version.

3) Poor/jerky shifting when car is cold.

4) Occasional reverse slipping.

5) Oil leak from the Selector Shaft Seal.

6) Oil leak from the trans pan gasket (always looked wet).

Mission:

1) Start with drain and refill with fresh trans fluid without dropping the pan.

2) Drive for a few miles. Stop and go through all the gears including neutral.

3) Drain the fluid and drop the pan.

4) Replace trans drain and fill plugs, gaskets, magnets, filter and mechatronic mounting sleeve seal kit.

5) Replace all solenoids and the white long gasket.

6) Replace mechatronic separator plate (B52).

7) Replace trans damper pistons.

8) Replace gear selector shaft seal.

9) Fill her up with fresh fluid.
