RD Logics Tranny Case

I have an RD logic trans case for a Tmaxx (currently on a SM). There were probs - the hole for the brake puck (little brass thing that pushes the inner brake plate) was not deep enough - not even close. Its hard to make it deeper without a milling machine and a flat bottom mill, but between deepening the hole and reducing th thickness of puck, it allows good brakes. Took time and needed a lot of had fitting.

The other prob was in shimming the trans shafts. The brg to brg inside distance in the RD Logics case must be larger than stock cause I had to use a lot more shims than a stock plastic case to cut the travel. If you get one, be prepared to do some work to make it work right.

It is a nice looking case though with a brushed alum finish versus the usual bright and shiny finish on others.

after doing the tranny mods I was thinking "this tranny really seems to be wimpy" but maybe it will be ok, but in the past vehicles I have run the diffs are the weak points and maybe investing in a set of 1/8 hybid difs is what I might need to do
