Beefing Up 3.0 Auto Tranny?
What kinda stuff can I get for the 3.0 auto tranny to make it stronger mine is going out and my friend repairs tansmissions for a living and I want strong as one as possible. You know one that takes a beating and keeps on ticking (not literally)
*I would have searched but I cant get it to work*

One of the main failures is because of poor pressures in the hydraulics. There are numerous upgrades that modify the valve body minimize problems.
Change your fluid fairly regularly or use full synthetic, keep it clean, and modify the crappy hydraulics that have had problems since the A4LD. Explorers and 4.0 Rangers have problems also due to the marginal hydraulic controls -- especially the 5 speed models.

I'm rebuilding mine soon because I have to take it apart to put in a 4x4 output shaft anyway. There are some excellent manuals on it from ATSG -- the Automatic Transmission Service Group. These manuals are used by many shops as the "bible" on such work. I have one and it's outstanding. You can get them on eBay and they're not expensive.
5R44E and 5R55E use the same basic valve body and the same aftermarket upgrade kits work with them. I don't know as I'd buy a whole valve body as they don't really "wear" -- I'd replace the solenoids and soft parts and put the shift improver kit in.
I just took apart an A4LD for some practice and to recover the 4x4 output shaft I need.

I got all upgraded internals in mine. My temps around town are about 145-150 and thats driving pretty fast and accelerating fast. All the hydraulics and valve bodies are upgraded, upgraded tq converter, shift kit and selenoids. I love it. it was way more than I wanted to pay, but my tranny is no longer the weak link.

They have the parts and manuals. There are some specialty tools that are required, which can be pricey. They're on ebay. The biggest problem is that the pump bushing has to be align-bored to the center of the bellhousing. If this is not done, you will buy another rebuild soon. There is a shop in Sacremento that can do this, if you ship them parts.
The trans delivered with the 3.0L is a de-rated trans (4r55e) from the 4.0L 5r55e. The clutches are different, and the basket stacks have different thicknesses. A guy on explorerforums.com documented how to beef up an A4LD using 5r parts, which was pretty involved.
