I bought a '91 R154 on craigslist and the input gear / 4th and 4th on the counter gear are trashed.
I am sad to find that these parts are not made and CANNOT be found anywhere.
It's especially annoying because the R154 and AX15 are very similar yet the AX15 has been reissued and you can buy a replacement for any part while the R154 has no parts available and has not been reissued. Below you can see these two wearing each other's bellhousings. The input shafts are almost the same length too.
It's also kinda sad to go through the work of retrofitting a transmission into your hot rod that has no parts being made for it.
What would it take to get someone to make parts for these again?I already called Midwest Trans, Aisin L.A., OMIX, every Toyota parts dealer etc.
If you're wondering, I put the R154 gears into the AX15 2WD case and into my AMC Hornet with a Jeep 4.0L bellhousing.
Now I want to make more of them for AMC people but if I can't find parts for the R154, it's hard to sell it as a better alternative to the T-5, which is pretty much the only other option under $3000 for AMC
