Damn, that sucks, sorry to hear that.

Again thanks for the info anyways my friend

Wow now that is a high stall. DO you run a aftermarket trans cooler? And how much power are you making?

The converter I run was originally rated to flash to 3400-3600 rpm's for a stock 4.6L 3V. Mildly modded N/A (CAI/tune) it flashed to 3800 rpm's. When the blower went on it pushed the flash to 4800 rpm's. With a centrifugal, my peak torque is just over 5,600 rpm's, so having the converter flash to 4800 rpm's - coupled with 4.10 gears - gets me really close to the powerband instantly.

I left the factory trans cooler alone, but change the fluid often. So far, it has come out bright pink with no evidence of heat every time.

My V2 is non-intercooled, the engine is 100% (sans blower) and the custom dyno-tuning is very conservative since this car is my daily driver. On a Mustang Dyno it made 364 rwhp at 6400 rpm's (my shift points). I suspect that on a DynoJet Dyno it would likely read about 395-400 rwhp due to the inherent differences in how they measure power.

I consider my car very lightly modded and am happy with it running low 12's @ 113 in the 1/4 mi.

I wrote this a few days ago:

....I also read about people running 200+ degree trans temperatures and with a correctly sized cooler, it should be much lower. You really want to be at or around 175 deg. Anything over 200 deg starts to slowly (or rapidly if the temp is higher) break down the fluid and varnish parts, causing clutch slippage and valves to fail. The seals in the transmission are either cast rings, teflon, or buna rubber. The cast rings seal off different components (stator support/tailshaft), the teflon is used on shaft seals between drums, and the buna rubber is used on piston seals and case sealing. The piston seals are probably the most easily affected by heat and they are only thousandths of inches from the clutches and steels, where a great deal of heat is generated. Let's also not forget, that the torque converter has a clutch with a piston and seals in it as well. Much heat is generated here also.

You are probably ok, but you and some of the other guys should definately check the trans temperature. If it is not "in check," it would be wise to get a better cooler (external). Changing the fluid often is a good preventative measure.

I own a 56 000 kms 2006 GT/-SC shelby. As I use a Kenne Bell supercharger with my 4.6 L three-valve I thought it wiser to replace the factory automatic transmission with a superstreefighter from TCI and, shifter and a 3500 TM torque converter, biggger fuel pump and huge intercooler as a preventive measure.
The only problem was finding someone who could do the programming effectively. we had to do it three times to get a satisfactory result. Works fine !! Other mods are Super snake wheels with 6 pistons at each corners and Michelin tyres, carbonfiber drive shaft and Torsen rear end and...of course 300 km/h speedo ! I raced it on Le Mans small circuit and it has been a more real eye catcher than recents Ford GT 500
