Just an fyi looks like e torx plusA few pics for fun:
1st photo draining and saving the new Ford factory ULV Trans fluid.
2nd photo shows the valve body and fluid pump removed
3rd photo shows the special External Torx head bolts that hold the stator in place
The adapter I made for holding the trans on my rotisserie engine stand works wonderfully.
We had what we needed to disassemble. No special tools needed, just some ingenuity.Cory,
You may be OK with the Sun Coast upgrade only, but the 10R rear clutch drum (E) is an on-off-on clutch pack that builds heat quickly.
More hydraulic pressure and quicker-firmer shifts will help a lot. That's why I am doing the TCM reprogramming as well.
10R requires some quirky piston compression tools, I hope you have some.
True road course racers run a manual transmission.question about the suncoast upgrades. I see that there is definite benefit for drag racers but do road course racers benefit from this? I believe their torque converters have a little extra oil capacity and there are some other benefits that might help.
