So im 99% sure tranny need rebuilt (off chance that it may be a solenoid but doubtful). I need to go with a stronger tranny rebuild kit (im around 650 hp) and im wondering wich to get. BD has the stage 4 master rebuild for just under a grand and have been told too stay away from ats any other ideas?

 

Really leaning too the BD any opinions?

 

SunCoast has a few options

 

I haven't used them but lots of goodies here. Parts toward the bottom of the page.

5R110W Performance Transmission 5R110W Billet Parts and Torque Converter

 

Ouch a tad expensive lol

 

That's the supplier I used for rebuilding my old trucks C-6. I went overboard on it and still saved money compared to a quality rebuild at a shop. They seemed very knowledgeable.
