    Hi all, since I only had this one unit to build yesterday I thought I take some pictures along the way. This particular unit is out of a 06 Nissan Pathfinder. Now Nissan has been dealing with failed radiators going back to the 1980s. This unit suffered the same fate. You can see the water contamination in the pan and other parts. A.jpg B.jpg c.jpg

    After I have the unit clean I like to start with the input clutch and sort of build the unit backwards.

    There are no shortage of snap rings and torrington bearings in these units. It uses 3 sprags also. 36301160_10217118435292883_6564177833361408000_n.jpg 36310071_10217118434932874_6323713704063926272_n.jpg 36318563_10217118435972900_713854204891889664_n.jpg

    One of the nice things about building these trans is the main shaft gets installed from the rear and can be put in last. Makes it easy because your not reaching around a shaft trying to install parts. 36347107_10217118432932824_5531652693082243072_n.jpg

    A bit of German engineering here, These 3 torx bolts you see hold the center support in. I first seen this on Mercedes 722.6 unit back in the 90s. 36371725_10217118431732794_4864697087226281984_n.jpg

    I didn't mention that when water intrudes in these units it takes out the TCM. It is integrated into a plastic module that holds all the solenoids and speed sensors. So we replace this entire unit with a OEM valve body. It will need a flash before it can function. 36333948_10217118431012776_3381889237786820608_n.jpg B.jpg

    Overall I really dont mind building these especially when installing a new valve body. Saves about an hour of work going though one of these valve bodys. Start to finish it takes me about two and a half hours to complete. But I have done many... 36353419_10217118431212781_6700588228065361920_n.jpg

    Changed the title to match the transmission.

    In the second picture on the second post, are the two right rings supposed to be sprags or bearings? They look like sprags, but none that I have ever seen before.

    I'm guessing the transmission cooler in the radiator springs a leak? I'm guessing they have to flush the cooling system for the engine too, right? That would seriously make me mad if that happened lol. Now I know if I get one of these (unlikely lol) that I need to put an external cooler on it lmao.

    Fantastic thread! Keep posting stuff like this. Even though I will likely never work on one of these, it is always interesting to me.

    All three of those are sprags. Not always necessary to take them out but the water makes a gooey kind of goo I like to clean out. And yes, a engine cooling flush and usually the overflow canister gets changed. It seems Nissan might have finally fixed their radiator problems tho, not good for us...lol I'll post more units but this is the first time I ever tried making a thread like this and its quite a bit of work, but fun...

    Ah yea, now that I look closer at that left one, definitely a sprag. I'm used to seeing the roller style, not that dog bone looking style lol.

    And you are right, making a thread like this is a complete pain in the butt! Below is a link to a thread that I created in Feb 2012 on my Camaro and the first write up took me a few hours to complete and match pictures to. Then, when Photobucket decided to pull their crap and stop third party linking, it killed all of the images and there was no way to download your photos and put them back on yoru computer. I was one of those people that, in order to save space on my computer, I would upload images to photobucket and videos to youtube and I would delete the original files from my computer thinking they would always be safe. I know better now and have more hard drive space on my network than any single person should lmao. Then when I moved the forum to Xenforo which we are on now, I had found a way to download all of my images from photobucket, and I deleted my account. What they were doing, allowing third party hosting, then removing it and not allowing you to download your own images, is extortion. They wanted $400 a year to give you your photos back. NOPE!

    So I paid I think $2.00 and used a Chrome app to download them and put them on my NAS (Network Attached Storage). Then I spend quite a long time finding the images and updating the thread in the link below as well as the article associated with the thread. I also had to do the same thing on another site that I moderate and have been on since 2004. Total pain in the butt lol. So I definitely understand.
