Hello...i have a IRS Tranny and i need help with identification. I dont open this. Only looking through the oilhole.
It is a DC Type3 diff with a aftermarket sidecover and i think a super diff.
Maybe anyone know this. Thanks

It could like transforms version of a pro street. They just did some questionable modifications. Transform were always cheaper than the other rebuilders.

I have a Transform swingaxle box in my garage I bought from them around 1993. It wasn't ordered "pro-street" with 4 spider differential and welded gears, instead their low cost baja special with a 4.37 R&P and an 0.93 4th gear. It's worked well for years but I don't have it in anything right now because of the low final drive.

You can put in in the various gears and turn the main shaft and count the revolutions on the IRS flanges to figure out the gear ratios.
There is a chart somewhere. |

If your count is accurate. It’s a close ratio 3rd.

You should pull this thing apart and clean it up!
Post up some pics.
I’m dying to see the inside of this one;
Curiosity woulda gotten me long ago.
Transform did all kinds of different things back in the day.
