Never heard of 'em. Jasper is supposedly ok, with a good warranty, but, it has to be installed by a licensed shop.

 

Martin Saine...Builds the best 46RE out there.
I think he's hooked up with "Flyin" Ryan.

I didn't know Martin Saine, so I clicked the FRP Tuning link. FRP/"Flyin'" Ryan in in The Woodlands, Texas.

I didn't see anything on the site about transmission rebuilds, so did some interwebs searching. Most posts I see that mention Martin Saine are older, but best I can tell he is/was connected with Fastman in Southern California:

My bad - Fastman appears to be in Wisconsin, but Martin Saine seems to be in SoCal.

 

I had a Martin Saine 46RE in my Dakota, only sold it when I went to John Cope 727.
