Anyone have any feedback on Coan Racing products?I have a TH350 I am going to rebuild for my Z this winter and am looking for a good high quality rebuild kit,one with everything?The trans was running/shifting fine and the fluid was red in the car I pulled it from but I have no idea the standard practices to rebuild an auto trans..this will be a first for meI'm a manual guy.Last TH350 auto I had was 8 years agon in my old monte carlo that I had rebuilt locally.I want to build this one myself.So my choice right now are either http://www.Coanracing.com or http://www.transmissioncenter.net/ the "raptor" trans specs are what I am looking at there.I plan to upgrade the Sprag(?) to the 36 element along with the couple of other areas I have learned about searching old posts here and talking with a few tranny shops.I also have the Ron Sessions book everyone speaks highly of.I've built motors and rears..now I want to dabble in trannies a lil.Any other suggestions are readily welcome also.Thanks guys!

 

Even if you don't have any feedback on Coan..what about tips to further strengthen/modify the TH350??Street/Strip car.

 

What is the transmission going behind?

 

Right now it is going to go behind my 350...4340 forged rotating assemble,Manley forged 10:1 flat tops,Afr 195's/64cc,Comp XE 274,Demon 750DP,Stealth,NX Hitman Plate and a 3.73 rear gear.Car weighs around 3300...its a healthy little small block addicted to crack.But I am also in the process of building a 400 sb that I hope to push 400hp/400 ft lbs NA RWHP all day long and then hit it with a 250 shot.So what I am looking to do is build this TH350 plenty strong with a nice convertor for my 350 and then in a year or so when the 400 is done..swap to a new convertor and not need to worry about the trans breaking with the 400?This is obviously my first auto trans rebuild and any all suggestions any experienced trans guys have...I greatly appreciate it.I already have the Ron Sessions handbook which I am currently reading through to understand the basics before I rip into this thing.

 

I have 1 of their race prepped TH400 setups and one of their custom built converters.... Ive had 0 issues with the setup...Its rock solid...Ive beat that thing BOOSTED UP off of the transbrake and its never missed a lick..
