After we loaded the Jeep Dodge A999 / A904 Transmission Rebuild Repair Manual on MINI CD onto our iPad, we saw the first image in the book. A detailed breakdown of the transmission and torque converter, we got to inspect its components. We started blowing up details to get a closer look at the valve body, the rear planetary gear set, the stator and the flexible drive plate. The next image was of the wide ratio planetary gears assembly. By the time we got passed the introduction and into the nuts and bolts of working on these trannys, we believed we were ready to go.

Of course, we looked at our A904 and realized ATSG, the publisher of this — and other - great transmission manuals had again filled us with a lot of confidence. While the read can make everything look easy, this is a job that only the experienced and brave should tackle. But the material on this MINI CD (PDF manual on the CD) is guaranteed to make the operation a lot smoother for the mechanic, automotive shop, restorer, rebuilder, teacher and student.

In our initial swipe through the digital manual, we learned:

• Where the vacuum must rise above or fall below the lock-up vacuum reference points to enter the lock-up position.
• What conditions will cause the torque converter to unlock.<.li>
• How line pressure affects the 1-2 shift valve and brings the lock-up solenoid into play.
