Adapter to fit the 6 Speed Allison Automatic Transmission to the Toyota Engine 22RE

thingiverse

This is a custom adapter designed specifically for those who want to pair their 6 Speed Allison Automatic Transmission with the Toyota 4 Cylinder Engine 22RE. If you've ever marveled at ericthepoolboy's ingenious creations (you can find them on Thingiverse, along with this engine model: http://www.thingiverse.com/thing:644933), you know that their attention to detail is second to none. In fact, ericthepoolboy's model of the Toyota 4 Cylinder Engine 22RE, including its manual transmission counterpart (http://www.thingiverse.com/thing:1094616), has impressed many a maker and has become an inspiration for those looking to experiment with their projects. This adapter allows you to pair your custom-made automatic transmission with the same engine model without requiring any major modifications. When installing this adapter, ensure that it is securely fastened to the case of the automatic transmission using nine 10mm-long screws with a diameter of 1.5mm each. Afterward, all you have to do is screw the bell housing to the adapter, which will require the same screws used for securing the manual transmission. **Update Log:** 03/13/2016 A crucial improvement was added in this version. A longer dipstick has been incorporated into the design of the automatic transmission adapter. This alteration was made possible due to the original model's dipstick being too short for optimal performance and compatibility with the Toyota 4 Cylinder Engine 22RE. 02/15/2016 Further refinements were implemented to ensure a smoother interaction between the adapter and the engine. The size of the input was increased to enable a tighter fit on the clutch in the flywheel, and an adjustment was made to increase the internal hole diameter for easier access to the transmission input.
