Which fluid to use in TR-3650? - 2003-04 Mach 1 Registry Owners Club

JeromeMach1 · 04-04-2011, 06:59 PM

I purchased a new 3650 for my Mach. The manufacturer and Ford say to use ATF. The tranmission shop that sold this transmission to me says to use 10-30 motor oil. I have never heard of using motor oil in a manual transmission. He says ATF is called ATF for a reason.

So, what fluid should I use?

Thanks,
Jerome

I used Mobil1 Synthetic ATF and Lucas trans additive. Search for the mixture, it is in the forum, that is where I got it. BTW, the Synthetic ATF smells really bad. haha

I don't see why you need any additive... Just use Mobil 1 ATF to the new 3.2 qts amount.

3650's are known for grinds & slight shifting issues. The Lucas seems to smooth everything out.

There are numerous Threads on the issues....

I just pick up Mobil1 ATF and Lucas for my Mach 1. I just bought the car a week ago and have had some of shifting problems. Today I am getting an oil change, transmission fluid change, and fuel filter change. I am hope it helps with the shifting. I will know tonight. I also have a MGW shifter on order.

What he said. No need for the Lucas in a brand new transmission unless you start having issues.

Mobil 1 ATF and 1 bottle of Lucas trans fix

Can't remember total amount of fluid but it's here somewheres.....

R-code17815 · 04-05-2011, 07:50 AM

The "secret sauce" for 3650's

1qt. Lucas trans fix & top off with a quality synthetic ATF

This tranny has a few "quirks" that the Lucas smooths out.
