3v trans

[Kenneth Crouch]

what is the best manual trans for the 3 valve or what is the best route to build the stock 5 speed?

Best for what?

Welcome aboard. The search button at the top the page is your friend. Lots of information on this forum going back 15 years.

If you want the best and got the money, google sequential tremec transmission.

 

[rocky61201]

My reply should have been, how much money you got????

 

[Midlife Crises]

If your going to put it in an S197 the T56 Magnum XL offers some good options.

Love my TR6060... But I do wish I had the separate bell housing of the T56.

Magnum xl.

 

[Kenneth Crouch]

Looking for the best to street and track the car I have been looking at the magnum but figured I'd ask everyones opinion that may have experience

 

[Midlife Crises]

I can recommend the T56 Mag XL with the 2.66 first and the .80 5th and .63 6th. It’s like a 6 speed close ratio.

The shifter location in the S197 is pretty far back, so it really limits your options. The TR-6060 and Magnum XL are both popular options, as with most things it depends how much money you've got, and how much power you plan to make.

Make sure you take the gearing for each trans into account per your application (ratio of each gear, spacing between each, rear gear and tire height options), I feel like that gets overlooked quite a bit.

Magnum = no shift linkage. Shifter is tailshaft mounted.

Did anything come factory with the T56 Mag XL? As in, anything to look for wrecked? Looks like they are quite pricey new.

Not as far as I know. Tremec designed the case specifically for the S197 using T56 internals, and for easy high rpm shifting. Those are the two major differences of the XL.
Anything from a wreck will have the remote mounted shifter.
If you don't care about the shifter being integral, then your best option IMO is the 6060.

If you're looking at the 1/4 mile track go with a built automatic. The stock 5R55s needs to be built to handle power. Other wise you can go with a 4R70W but I don't think that has an overdrive.

The 4R70W does have an overdrive but it only has four forward ratios:

• First: 2.84 :1
• Second: 1.55 :1
• Third: 1.00 :1
• Overdrive: 0.70 :1
• Reverse: 2.32 :1

A Lentech built 4R70W would be great for the dragstrip. The only downside is the widely spaced ratios so you need it to be bolted behind an engine that has a wide and flat torque curve.
The 4R70W was manufactured in large numbers so it's easy to find one cheap and have it built. Just make sure it came from a Ford model with the 4.6 Modular engine so that it has the correct bellhousing bolt pattern.

If you're looking for a manual tranny, the Tremec T56 Magnum XL is a great choice and you can choose a set of ratios that fits your needs.

I wanna build the car to be around 800 wheel HP
And have tossed up whether I should get 3.73 or 4.10 for it just haven't quite decided yet also plan to make it s/c still debating beans on that as well

 

[RED09GT]

Tremec XL is a great transmission but like all transmission swaps these days, they are very pricey.

Due to the astronomical costs of getting one in Canada, I elected to go with a used TR6060, a used McLeod RST clutch, a new aluminum driveshaft, and a new MGW shifter for about 1/3 of the price. The shifting with an MGW Gen 2 shifter on a TR6060 is light years better than a TR3650 with a barton shifter.

Get the 2.97 first gear if you are going to drag race it.

This ^^^. I'm seriously considering it for my NA 4.6, specifically for the close ratios.

You'd be saying goodbye to the big gap between the 3650's 2nd and 3rd, welcome to a much more usable 5th, and you still get to keep a fairly lazy top gear ratio for highway cruising. But choose your axle ratio and tire sizes carefully - 1st is kind of on the tall side and most people are probably going to want 4.10's.

I agree with Red, you'll want the 2.97 low with the 0.80 / 0.63 overdrives for drag racing. But maybe keep the 0.80 / 0.63 overdrive ratios. The 0.75 / 0.50 overdrives might be too tall unless you've added a fair amount of midrange torque (i.e. forced induction of some sort).

It depends on what kind of power or torque you're making. When I was talking to D&D performance about mine, they advised for stock or near stock (like a N/A bolt-on engine), you'll want the 2.97 T56 since the 2.66's ratios are too tall to be fun on the street. For an engine making a lot more, you'd want the 2.66 since it can handle the taller gearing and you'd be shifting too often with the 2.97. Based on my experience with my car, I'd agree (350 RWHP, 2.97 T56)

I did have the overdrive gears swapped in from the 2.66 into my 2.97 originally, it was a huge drop in RPM from 4th to 5th and I'd be doing 1500RPM on the highway. Good in gas milage, but had to downshift to go around people it even going up big hills. Glad I went back to the standard 2.97 ratios. This is all w/ 3.73's in back, BTW

 

[NickD87]

Anything over stock power the 2.66 first will be faster for drag racing as well
I am around 500hp and have a 13 6060 with the 2.66 gears and 4.10s and it awesome, if I had more power I’d step down in rear gear. I had a road course day on a shorter track this week and was thinking how much I loved the trans vs thinking back to when I ran the 3650 (both with mgw)
