If you have a good Tranny Shop which is familiar with MB gearboxes go to him, as others have said it's a reasonably quick job and should be available off the shelf, mine was done a few years back and it was a day job by a Tranny shop, price was around the $600 mark with oil and filter change and new plug fitted, he sourced the parts from the MB dealer.

Looks like is not the battery.

Drover's sticky has how to replace the conductor plate and the solenoids:

Also try
http://www.sprinterparts.net/mercede...ter-parts.html
or some of the other sites listed in the sticky to compare MB (well Dodge Sprinters) with Jeep part numbers.

Update: I found one MB dealer that had the solenoid in stock and they express posted it up on Wednesday, fingers crossed it gets here tomorrow morning so i can get it installed! I wont mention how much they charged for it Here's hoping that this is the cause of the last of the problems!

Did you find out which position or solenoid it is if you are doing it youself. Don't forget there are 2 side by side that use the same solenoid.

Fitted a Tranny Cooler to the Grand, once I got the brackets right all was good, ran the hoses down ànd they ran well with no hard bends, made my own anti chaff for the hoses using some trickle pipe which I sliced in a corkscrew cut.
On the test run it was 34 deg and my temp gauge was lower than normal when I run thru the hills near my place, so the cooler is doing it's job. Torque showed my coolant at 73c, pity it doesn't show tranny temp. Made 4 seperate brackets and used some rubber pads with the bolts to try and absorve vibration which is th biggest worry I think.
The oil is running thru the cooler first then the radiator as I want to stop the tranny from causing high coolant temps when the tranny is working hard.

Good work Drover. How much clearance did you end up with to the grill/headlight fascia. Does it sit just above the front body member or does it drop below it a bit.

I would love to see a trans temp readout and a test as to whether the temp is better when plumbed before or after the radiator. I see what your theory is and it has merit but I also wonder whether given the size of the typical trans cooler whether it would actually run more efficiently if the initial heat is removed by the radiator. Plumbing before means the cooler can never cool lower than radiator temp regardless of the situation. After means it can in theory. Course it could all just be a case of tomato, tomarto but I've always wondered. I know when the Toyota Surf guys were trialling their cooling issues it was put down to the trans temp inflating the rad temp. Cause was a too small for Australia torque convertor compounded into a badly designed trans cooler in the rad. But they found with their constraints that it was not as efficient to try and run without a rad cooler and best option was better flowing rad cooler design and POST rad trans cooler.
