I just bought a suncoast Transmission for my 7.3. Told them I wanted it to withstand a minimum of 500HP (not that im shooting for that, just to be safe). Also purchased the extreme tow cooler, billet input shaft, torque converter, and deep pan. I was wondering if anyone else also has a sunco and how they like it.

 

I have a full suncoast tranny... I would have told you to save your money on the input shaft but...

Get a C-6 foward drum, they are fully splined, the 4r100 is not.

 

what is a C-6 forward drum? splined? and im assuming you are happy with the tranny though? thx

 

How much did u pay for your Suncoast? I agree with Joe, go with the C6. Or just stick with the 4R100 drum for now and if anything happens to it, get the C6

 

Yes I am happy with it...

C-6 is a earlier automatic. It will hold more HP...

 

Joe did u put a C6 drum in yours?

 

Yes, After I spit the splines out of the 4r100 drum...

 

awwww, ok

 

Got everything for about $4800 with 2 year unlimited warranty, tried to get them to match ats 5 year warranty but failed. My tranny blew when we were on vacation for new years got stuck 15 Hours from home for almost 2 weeks. Family finally came and towed my truck and trailor home. Been wanting a sunco for awhile, and thats what it took to finally get it. A C-6 is a full tranny? still dont understand fully, still learning about my truck and i can never get enough knowledge! thx for the help and input.

 

Aww ok what?

Doubt it?

Would a graph help you understand?



No problem... C-6 is a tranny that came from the 70's era fords. What you want is the foward drum out of one to install in your 4r100. Talk to suncoast if thats were you bought it and tell them you want this because it is fully splined.

They will want to sell you one of there fully splined Billet drums for about $900, you dont need it.
