They advertise "Engineered to facilitate installing a Chrysler 518 overdrive automatic transmission into a Dodge/Plymouth Mopar A Body car. Requires additional fabrication and welding."

I figured the additional fab and weld was the tunnel mods.....

When I talked to them they said the transmission will fit but they built it for a customer who said he would make it work. The owner told me to wait and purchase the tunnel kit they were developing. I’d expect to run out of room between the top of the A518 to the bottom of the floor before I get the correct and optimal drive shaft angles.

I’m using the a500 that has a narrower girth where it matters between the bell and the overdrive. I will relieve the aluminum case and dimple the tunnel to massage more room.



Here is a picture from another members build showing the contact spots were the tunnel of the A500 hits the floor and where he dented the floor pan to make room.
