I was wondering if anyone uses GM synchromesh in their T-45 transmission? What do you guys think of it, do you recommend getting it, and do you know how much fluid I need to change it? Thanks

 

Use fords new fluid they recommend for those transmissions

 

Do you know the name of it?

 

Same as the auto trans fluid, ford now recommends to put mercon V (5) fluid in the manual trans. The original fluid ford used was a gear fluid, and too thick to get good circulation inside the trans, the thicker fluid would also cause a feeling of tougher shifts especially when cold.

 

So do you know how many quarts i need to change the fluids?

 

Do you have the vin for your car? If not, what year is it? With the vin I can pretty much tell you everything about the car

 

i have a 1998 GT, all stock

 

Ok, the fluid is Mercon multi purpose ATF trans fluid part # XT-2-QDX and capacity is 3.2-3.35 quarts.

 

I am using AMSOIL synchromesh in same tranny and 3.5 quarts. I was having minor grind and engagement issues til I used AMSOIL which have since vanished. And it's good forever. Change it the next time the spirit moves you

 

I've heard RP changes worlds.
