I have just bought a '99 GT with a 5 speed and want to know what transmission is in it. I was told that it's a T5 but I have seen other stuff that says it's a T45. Can somebody tell me what's in there? Thanks.

 

I have a 2000. 99-00 have a t-45 and Windsor heads and block. In 2001 they moved to Romeo. The only real difference from Romeo to Windsor blocks is Windsors came with 8 bolt flywheels,Romeo have 6 bolt and the heads are same but different bolt pattern and oil fill is on opposite side. The t-45 was scrapped in 01 and the t-3650 came in them. The t45 are very similar to a t5

 

the tr3650 swap was mid year, the early 2001s still have the t45. Just to let everyone know.

But yes the 1999 has a T45. The V6 cars had the T5.

 

So 2001 was a mid year change. That sucks.

 

My bullitt has the 3650 What's yals opinion on that tranny. Its kinda clunky

 

Very good information. Thanks Everett and Knight. I did wonder what was down there and did not know about the differences between the Windsor and Romeo.

For sinisterbullitt, in my case I'm coming from an Isuzu Amigo so anything is an improvement. It does seem a little notchy but I'm getting the hang real quick. I have tried to start a couple of times in third instead of first though. The short throw compared the truck is great and I know that can be improved upon too.

 

Anything can be improved

 

Windsor heads have 13/14 bolt valve covers. Romeo are 8 bolts and the oil fill is opposite too. Be wary of these differences when buying used parts.

 

Everett do you know anything about the 3650

 

Other than it's an 11 inch instead of a 10.5 like the t45 and t5 nope. Sorry

 

The 3650 is a fine transmission, they used it through the 2010 GT. My brothers bullitt with a triax shifts great, its notchy but I like it as you know if you are in gear or not for sure.

All bullitts have the tr3650. I think the bullitt production started with job 2 and thats when the switch occured. Somthing like that.

 

t-5 from 1996-2004 is v-6
t-45 from 1996-1998 v-8

Yea I know thank you tho. I was just getting yals opinion on it. I'm glad its good. I'm going to get me a steeda for sure

 

Ok what do yall think of doin an auto to manual swap? Just like to hear yalls opinions

 

Hell ya.....way more fun

 

Yea its definitely more fun but like what about the conversion? How difficult would it be, would i need to reprogram the comp, like what woild i need to do?

 

You need the pedals and tranny from the donor car and I don't think you have to re-program anything. Bolt in. But make sure you take EVERYTHING from the donor car.

 

Arent there some differences between the exhaust setup with auto and manny? Cuz i see alot of midpipes and headers that say "for manual transmissions"

 

I would say heck Yea convert it but people I know that have are always tweaking, replacing, cussing so on so forth

 

I want to but i think ill wait till i save enough tp build my own engine then swap to manual
