ok im searchn the web for the circle d tranny stuff everybody has and i seen there is a circle d specialties AND a circle d tranny website... so my question is are these two in the same and just seperated the converters from the tranny shop or are these two totally different places of business? and what you think bout them??

 

Only one im familiar with is Circle D Specialties. I have their Trailblazer restalled 3000 converter on my 08 5.3L. It works great! and it stalls straight up to 3000.

I did have to upgrade my trans cooler because I was seeng upwards of 200+ degree trans temp. I got an oregon performance 40K GVWR trans cooler. On hot summer days it stays under 160. Floor it, it'll rise to 180 but will drop quickly.

Dropped 2mpg in the city, highway MPG remained the same.

 

Circle D Specialties. If you check the Drivetrain Section there is a Huge thread on their base model converters.

 

well i looked and there both based in houston, tx so i wasnt sure if it was the same two ppl so thanks.. and i seen that the circle d trans had upgraded clutches and valve body work for my 6 speed in my truck and are currently testing the new shafts and drums they had built for the 6 speed as well theres a video on there website bout it.. thats what im lookn for!! but anyway yall kno anybody that builds the tranny thats really good for the 6 speed both that will last and perform well??

 

thats what im looking for! , i need heavy duty clutches for my 6 speed.. dnt wanna run into problems...

 

Circle D does BOTH! Chris deals with the converters, someome else deals with the tranny builds.

i have a Circle D 3000-3200 in my CC and my WT with the full bolt on 5.3 swap. its worth the 375.00 for a brand new converter.

my truck runs 14.4 @ 94.89mph stock 5.3/60e other than the servos.
its got 3200Circle D/LTs/ORy/90mm TB/4"CAI/Truckshop Tune

 

circle d specialties? or the other circle d (circledtrans.com)??

 

circle D does both. they are the same company.

 

actually "different" companies but both owned by the same family. chris owns cds and i think its his parents who owns the CDT. 2 buildings parked next to each other. one only deals with transmissions, and the other only deals with converters. Both have an awesome reputation.

 

SWEET thats what i wanted to kno! now i feel better haha
