ive tried finding Flat Ernies " ultimate T5 " thread but can't find it for some reason.I was going to tag this on there but anyhow here is a link to a nice looking little Tremec that might solve a problem.Its written in Spanish I think, but I guess you could get a translation if someone would oblige.Sorry if it's been posted before but I thought it interesting. https://es.wallapop.com/item/manual-reparacion-superduty-tremec-tr-4050-234164606
That Tremec 4050 must be quite heavy duty given it’s advertised use.....to replace one ton truck transmissions.....interesting Ray
Here is the spec page on it. It's a granny-gear truck transmission. The ratio spread isn't performance oriented. I'll consider it to replace the NP435 in my old F250 though. http://www.tremec.com/anexos/file/tremec_tr-4050.pdf
