These images are oriented from the bottom looking up as the transmission would be installed in a vehicle.
This was a jeep transmission with a bad (overdrive) gear set. A used unit would have
been very expensive, if one was available, as this malady was a common problem.
The drive gear was removed from the tail shaft before the images were taken.
The drive gear rotated, in relation to the countershaft on which it was mounted, on caged rollers when it was not engaged. If the manufacturer had used loose rollers, it would have had better support due to more rollers. Smaller loose rollers, or 'needles,' would have been even better. Another design option would have been a sleeve bearing. When the gear was loaded there was no movement in the bearing interface.
A spacer sleeve (pic 05) was made to hold the space the bearing occupied. The retaining ring on the end of the shaft was needed to hold it in place axially.
The assembly was shifted into the engaged position and held in place with a plug (pic 05) behind the detent ball. A detent ball was removed from the case between the shift rail and the one next to it that was designed to keep the transmission from being shifted into two gears at once.
The result was an affordable repair without overdrive.
I have to get my transmission repaired soon. It's starting to skip gears and gives jolts to my car. It usually happens in the winter time as well. I think when I get this repaired, my car should be fine after that. http://www.coronacarrepair.com
