Description:

Stage 4 T-56 built by Six Speeds Inc. back in '09. Approximately 1K miles on build, car was in storage from '09 until last year when I built a turbo combo for it. I plan on greatly exceeding the power capacity of this trans ( it's rated to 700 RWHP ), so I want to sell it so I can upgrade. Will come with a stock LS bellhousing, Quicktime is NOT included. Slave cylinder not included. Shifts like butter w/ Hurst Billet Plus shifter, which I will include. Trans is still in the car, and I will only pull it once I receive a deposit. Will ship on your dime. 2.66/1.78/1.30/1.00/.74/.50 ratios. Have videos running through the gears from this past fall. Build includes: New 1-2, 3-4, and 5-6 sliders, new reverse slider, new 1-6 gears, carbon fiber syncros, 3-4 billet keys, bronze fork pads for 1-4 gear forks, steel 3-4 fork, new main shaft, and new bearings. Asking $2750 OBO.

I just did a quick quote from UPS and it said $316 to ship 150 lbs. to there, which is what I figure the dry weight is with packaging. I'd do $3K shipped, and I'd cover the PayPal fees.

Yes, I still have it. About to put the car up for the winter next month, so it'd be the easiest time for me to pull it. It's such a killer transmission, I've been dialing my car in and when I'm at the track, I've been shifting close to 8K and it shifts like butter. You couldn't do that with a stock trans. Unfortunately for me, I can't turn my car up until I swap in a Magnum-F so it has to go.

I might be interested. I am looking at the magnum F as well. May be overkill for what I’ve got (600rwhp) but my stock t56 isn’t gonna last much longer. PM me your best price shipped. (Pa)
