Default 5 speed transmission

Hi,

I love to cruise in my 69
I have 3,70 rear, and I have the change to buy a old 1990 T5 World Class 5 speed transmission with 0.68:1 in 5th gear.

Is this a good combo?

Is a T5 a Tremec? I lose track of all the acronyms somedays. Even if your rear ratio is higher numerically, I would say yes, good combo. The 3.70's should be fine when used with tires that are near stock height, 26.9" - 27" tall.

Any trans that has overdrive has to help highway cruising, both in terms of less engine rpms and greater satisfaction of enjoying the car more often.

There are a few folks here who have installed the T5. I'm seriously considering it as a replacement for the stock 4 speed.

Just make sure you get a T5 that was designed for and was behind a V8 and not the V6 version. Tougher to find the GM V8 version but can be found in the $500-$800 range.

I just got this info from the seller.
Gear:
1 2 3 4 5
3.35:1 1.99:1 1.33:1 1.00:1 0.68:1


Can it be this tranni:

Mustang

Introduced in ’83, the T-5 arguably gained its fame in the Mustang 5.0. The first to take the step up to WC in ’85, Ford used the T-5 through the Fox-body & SN-95 chassis ending in ’95. The strongest T-5 available was found in later Mustangs and available through Ford’s Motorsport & SVO operations.

Available with a few different gearsets, the most common gearing was from ’85 through ’95:

1st – 3.35 2nd – 1.99 3rd – 1.33 4th –1.00 5th – 0.68
