03-04 gt 3650's question

Mr. Rustypwnz · Jul 29, 2010

do they have the .62 OD? or the .67?

just wandering, might be going to a 3650 on my car as my t45 hung its self..

0.62, I believe. ~2000 rpms at 75 mph in my 2003 3650 5-speed with stock 3.27 gears.

ditto for my '03. its tall! to be honest, i would prefer the .675 of the T45. I dont really get into fifth unless im going 50 (~1200 rpm) or more, and even then, I cant really pull a large hill or pass. My brothers '00 GT with the T45 is much easier to live with day in and day out. Hell, I havent even noticed an increase in highway gas mileage with my airplane fifth gear lol.

Then again, if youre going to get some rear gears in the future, it might help to get that .62:1.

I just put a 3650 in my 96. I didn't notice a difference for 5th in the limited time I've had on the tranny before I blew a throw out bearing but it does shift a lot smoother than my T45 did. I have 4.10's in mine so it may not be as much of an issue.

.67 came in the GT and .62 in the Mach.

Nope. Im pretty sure all '03 and '04s got the .62:1 - that just happens to make 100% of machs have the .62. But '03 and '04 GTs also have it.

wikipedia is wrong, and one of us should fix it.

I remember on my 03 gt, the from 4th to 5th was big....bigger than on my friends 2002. Ay 80mph I was turning barely 1500-1800 rpm or so. It was awesome.

So I believe it was 0.62 as well.

I just finished swapping in a '04 3650 into my 96 and didn't notice much difference if any on the 4 to 5 shift. Now if I can just finish with the speedometer crap. Overall I like it more, but i'm used to tremecs in general so I guess I just feel more comfortable with it over the "smoother" t45.
