Transmission Upkeep

Hello,

I'm trying to have some preventative maintenance done on the 5R55N Transmission. Basically, I'm going off of this thread: https://www.jaguarforums.com/forum/showthread.php?t=45131&styleid=5

I have a few questions that are probably obvious to most people on this forum.

What size Magnefine in-line transmission filter should I buy? 5/16 or 3/8?

How many shift scheduling springs should I buy and where do I order them from? He said in the thread that the shift kit comes with 1 already.

What kind of pan filter do I order?

Can someone direct me towards a new solenoid block? He said he bought his for $100, but I'm having trouble finding one for less than $140 and it also seems that the ones I find are used.

Is there a general consensus about the type of transmission fluid we should buy for the best price and quality? If so, which kind and where should I buy it? I'm located in the U.S. if that makes a difference. I've seen on other threads that people in the U.K. are not able to get some of the transmission fluids we can in the U.S.

Mercon V for your fluid. The block you can find from www.sonnax.com as well as the springs. And as for the in-line transmission filter, I wish I knew myself.

Hope this helps!

+1 on Mercon V Trans fluid. I had my 5R55N Trans built and I use Mercon V with no issues.

Very helpful! Although, on that website I can only find a remanufactured solenoid block and I can't find the springs. Should I be buying remanufactured or new? And are the springs called something else that I'm not aware of? Thanks again!
