Surreptitious.....

[oldeskewltoy]

Sooo.... length (body opening and shifter cup) appears to be pretty good, the opening should allow the shifter cup to clear the cross member. So now that the car is prepared to accept the new transmission, we need to see what the transmission needs to fit the car.........


a quick 2 panel show the current mounts for the 2 transmissions. There are a few obvious issues to overcome....



1) the J160 mount is about 3 11/16" further back then the mount on the T50 (AE71 T50 mount)



and 2) the J160 mount hangs down significantly more (almost 2" lower overall), and 3) The T50 mount is NOT spaced evenly from side to side, while the J160 is evenly spaced.


Because of the amount of drop, AND the uneven side to side spacing the original cross member was discarded... to begin the brainstorming once again.......




If you stare long enough... the J160 mount begins to "tell" you the mount it "wants" (Thanks to Miura (Jeff) he saw it first)





So now that the mount has designed its own shape... we let the car design the rest of the shape... now the problem we have is the J160 mount is too far back to fit any of the area Toyota designed to support transmissions in the AE71....


You can see the T50 cross member fits the 13" span by how clean it is.. also if you look carefully I've drawn a small area inside the trans hole that represents the location of the J160 mount in relation to the floor


So the mount needs to sweep, or "wing" forward.....



Yes... that is corrugated paper for now, the mount itself is being built in 1/8" plate... I should have it for test fitment on Wednesday. Once the crossmember has been sized, gusset supports will be added to reinforce the plate.


More to come
