where to buy a trans-break?

pts

extreme automatics

ck performance

thats some main ones. almost every vendor im sure can get you one
 
thanks guys. one more question, if you had to replace 2 or 3 parts in the trans with billet replacements which ones would they be?
 
With the trans brake I would do billet forward drum, input shaft and if mid to low tens with sub 1.5 60's a OD sun shell and planet as well. Call Lonnie he has everything you need he makes them in house
 
CK actually makes his own parts and sells quite a few of them to various vendors. CK would be my choice for billet parts as well.
 
The input shaft would be hte last of the billet parts.
Forward drum,OD carrier and Ring gear.
Call CK he has the best pricing ive seen
 
Id go for the forward drum and carrier/ring gear first. I have never seen an input fail in a car slower than 10.0. In all the 200 4-R's ive done in the last few years 25% or more have cracks in the carrier splines.
 
I am not saying it hasn't happened,but in my 22 years of building 2004rs I haev never seen a broken input yet.
so if your on a budget leave this out,but it is for sure cheap insurance if hte trans has all the other parts also
