How to make T56 hold up in high HP cars. I feel the biggest problem running a T56 in high hp cars is the lack on lubrication on the head set gear and front gear on the counter shaft. After tearing up 2 G-Force gears I studied the gears closely and discovered that the gears were messed up because of lack of lubrication. Under hard acceleration where does the fluid go?....yes to the rear of the tranny, leaving the head set gear dry and that gear is supplying load through the counter shaft in every gear except 4th gear.
I decided that I wanted to rig up a pump so that I was always spraying fluid on the head set gear. I looked around and found a 12 volt electric gear pump and so far so good. I just got finished taking my tranny apart to inspect it and the head set gear and front counter shaft gear still look brand new.

In a situation like yours where the car is probably face plated and a pure race car , I would play with fluids instead of worrying about spraying it on the gears like you have done .
I would think a full synthetic race fluid like the stuff Synergen offers would cling to the gears for a long enough period until the car came down and the fluid leveled off .

as well, i believe that a year or 2 ago tremec added a pump to the t56 transmissions to send fluid up to the front where the trans is being starved of lubrication on hard launches, just what i heard. i turn my pump on when i run the car, otherwise it is left off, no need for it tio be turned on when driving the car on the street. i too have seen the same type of problems in the past.

correct! i added a pump filter and cooler 2 years ago. it is money well spent!

The OEM pumps on the LS7 and late model T56s just circulate
the fluid for consistent temps, no spray bar, just dumps the
cooled fluid back to the top side of the case, right where the
alignment bolts are.

i installed a weldon pump to handle circulation, i even had Kinsler flow it, and turn up the pressure to be on the safe side.

slowhawk,
that is a great idea, i mean i have the fast turning all sorts of **** at WOT, lol!!! i am pretty sure I still have one more output I can utilize.

If you overfill, you risk airating the fluid and causing friction damage. If you do overfill, you need to make sure you add anti-foaming agents that don't change the ATF friction/lubrication properties..

redline atf d4 is good fluid, as well as synergyn fluids. that is about the only reliable product i purchased from G Force, lmmfao! hey i just made a funny. i figure it is a good product as it is puchased from a good vendor.
hey Taner. liberty told me to use syncromesh with the faceplate. Have you found something better?
I see you have a McLeod Blowproof bellhousing. Did you check the bellhousing alignment when you installed it? The McLeod Blowproof housing is notorious for it's bad alignment, particularly concentricity. If the input shaft is poorly aligned, the headset gears would not run parallel to each other and may become damaged from missalignment. Just a thought.

This is simply not true. The installation of this bell REQUIRES the alignment of the bell to the engine pilot bearing as a basic step. You cannot just bolt it up & go. Anyone with alignment problems simply did not follow instructions.
