Awesome rebuild kit especially with the added extras to upgrade the holding power all in one spot. Kit shipped well packaged with everything as advertised and quickly. Can't wait for my billet internals to come so I can build my trans. I definitely be coming back when I build th400

Great kit for my 69 Camaro
Came with all the parts to rebuild my TH350. As advertised. Came with the black coated kolene steels and red HP clutches. I purchased it after work, they shipped it the next day. Happy with the purchase.
