AR-5, r-154 Anybody actually done this

First gear is nearly useless in the ax-15 with my 3.23 gears but this winter I'll be swapping in 2.76s and that'll change it a lot. The AX with 2.76s will actually have almost the exact take off as a low first gear 904 with 4.10s plus you get 2 extra gears over the 904 as well. Here's a comparison between the 2.

One big advantage that I believe the r154 would have over the ax-15 is smoother shifting. My ax does good for what I use the car for, a driver with some spirited takeoffs, but it's not the smoothest shifting. That said, another change I'll be making this winter is draining the oil out of the trans and going with Redline MT-90 or Redline MTL which, according to many jeep owners, does wonders for the shifting.

Yeah that is nice. I like to use amsoil. Used redline and its good but man the amsoil stuff is like butter. That would be the advantage to the r154. Mainly I am really looking into the Colorado Mr5 or Ar5 what ever its called. Good gear ratios and cheap. R154 cost $1200 these days. A colorado transmission can be had at the pick and pull for $250 at a local salvage yard. Making it a good candidate. Thinking we may just do this. Would be nice if we could get a pick and pull day going. Find the Colorado transmission and have the other team pull a bellhousing. Mate the two up and checkout. They would not know the difference and we could walk out with what we need.
