I have a machine shop project that requires a Planetary Gear for a gear reduction. Although I could build it from 'off-the-shelf' gears, it would be much more cost effective if I just used something like those in automatic transmissions.
I've worked on a lot of car engines and a couple manual trannys but never torn a AT apart. Most, present day shop manuals have little or no info on the make up of ATs or Manuals. Therefore I don't know how much trouble it will be to get to these gears.
I went to the salvage yard to day and every AT I saw, out of the car, was a front wheel Transaxle. This further complicates things due to size and the differential stuff.
Their was one AT from an older rear wheel drive sedan but it was a monster and I know I would have trouble even getting it into my PU.
Maybe I should look at something from import PU.
Another thought would be to go to a transmission shop and ask them for something they will be disposing of as scrap or core.
I know the size and ratios will vary between makes/models, but I can deal with that in the input belt drives.
Does anyone have any suggestions.
