Good day gents,

I am finally getting around to swapping the lines below and was hoping to get some guidance before I dive into this, this coming weekend.

I am changing the lines due to a leak that developed at one connection after I swapped the 55 into it. Instead of changing 1 I rather change them all.

After the swap I followed all the proper directions to refilling the transmission, but since fluid has been leaking I am second guessing myself on how to go about this.

My initial plan is to remove each connection point, collecting the oil the discharges from them, measuring how much fluid was loss, replacing it, then adding as needed ( fill line @ 80c etc.).

Is this correct? is there something I'm not thinking of that I should be? My second option would be to do the mechanical work, tow to an MB Indy shop and have them perform a complete flush?



All help is appreciated

Sounds a good plan. I also try and measure the ATF removed and replacing the same quantity as a starting point. Bring the ATF up to 80°c and measure on the transmission dipstick and bring up bit by bit to the mid-point of the top and lower measurement marks. I assume you have the special dipstick as the vehicle doesn't have one from Factory. They are easily available and cheap also.

BTW what are the pipes #91 for as I don't recall seeing them. May be totally wrong though

Thank you man, yes I have the dipstick I will follow those steps.

The 91 is the feed and return of the coolant to pump and back I believe. I may hold off on that for now.
