Hi all, I'm working on a project to mate a Toyota Supra R154 transmission to a Dodge Neon SRT-4 motor using a 2.4L Jeep Liberty bellhousing. Everything bolts up, but the input shaft does not reach the pilot bearing in the block. I can probably mill the bellhousing to make this work, but I wanted to see if anyone had any ideas. It's a little less than .25" different.
I looked into swapping an AX15 input shaft onto the R154, since they are very similar; however, from what I understand, the AX15 is a 29 tooth gear and the R154 is a 34. I also know some of the Supra guys have been swapping over the an Aisin AR5 from a GMC Colorado, no one seems to have compared input shafts to see if the AR5 shaft will work in an R154 though.
I have heard rumors about a 4WD R154 with a longer input shaft, but I have not seen anything to support this.
If anyone knows of a longer input shaft that will fit on an R154, or has any other suggestions on how to make this work, I'm all ears. It's a small difference, but I'd like to avoid milling the bellhousing.
Thanks,
Chris
