AR5 - a better explanation is this. GM contracted with Warner and Aisin to build a transmission for the Colorado and other light trucks. This is the transmission they designed. Functionally, a AX15, but it has 26 spline input and 28 (IIRC, it's whatever a 700r4 is) output. It doesn't have the 6 bolt rear flange, nor is the same as the 700r4 or 4L60e.... which means the adapter is custom made.... although the adapter for the output is merely a 4L60e output. It was a fair bit of work to adapt, but it's a stronger transmission, it's 80 lbs not 200 lbs like the NV4500, it was free to me, and if it doesn't work I'll put a 4L60e in its place.... which I already have on my shelf.
moving along
adapter off
ugly... but not rusty...
dagnabit... now that's ugly and must be replaced
if the shims hadn't been trashed, I'd have reused these... for those who count - there must be 48 of these.
.... 42 - the answer to life, the universe and everything, but not the right answer for Dana 300s... I think I found 5 of the missing 6.
if you get lucky, you don't have to pull the lower gears out
the new bits
and yes, this fought me, but I won
anyway, cleaned the case up, I'll paint it tomorrow and hopefully have the instructions so I can put the upper half back together. I'll be waiting for the intermediate shaft to arrive; but I bet that's at least a week out. Which is good, I need to re-order a seal and do a bit of cleanup on the transmission....
ttfn.
