Mustang T5 Manual Transmission Conversion Guide

Mustang T5 Manual Transmission Conversion Guide

T5 conversions are possibly one of the most requested about change for the older Mustangs. We are going to cowl two areas of confusion. First, what yr and model to look for. Second the ins and outs of really doing the conversion.

Which T5 transmission do I want?

Through the years, Ford made many improvements and variations of this transmission. Actually Borg Warner made the enhancements after which Tremec made some greater. The T5 was delivered in the early eighty’s. In 1985, the world class model became delivered and turned into used up to 1995. Each yr, they were advanced on growing the torque capacities and fine. The 1994-ninety five fashions are essentially the same internals because the previous years however, they have got a longer enter shaft making them not the manner you need to go for this conversion. The 1986 to 1993 versions are the high-quality for the change. Little facet observe, 4 & 6 cylinder T5 will not paintings! These models have a totally low torque capacity and exceptional enter shaft diameters.

Ford Racing now offers the M-7003-Z Heavy Duty model. 330 lb-feet and a steel input shaft retainer are some of the high lighting fixtures of this transmission. This one by some distance is the pleasant one to apply.

One other observe, Tremec gives different 5 pace options just like the 3550, TKO, four hundred/600, and so on. These models are closely upgraded 5 speeds however are also re-designed for some critical horsepower applications. They are large in length and require change to the tunnel in addition to a custom pass member. The T5 go member will no longer paintings with these transmissions.

Ok, permit’s observe the transmission up near. The enter shaft is a trendy 10 spline and well suited with the early 10 and 10.Five grasp disks. The front electric plug is for a neutral protection unit that isn’t always used while doing the change.

On the motive force’s facet, half of manner down the housing is a 2 prong switch. You guessed it, again up light transfer. This may be utilized to paintings but will require some electrical transforming.

Under the tail shaft housing on the motive force aspect is the speedo cable establishing. This is the identical diameter as the older T-10, Top Loader, 3 velocity, & c-4 vehicles. The speedo driven equipment remains the antique layout and in some instances, well suited with the vintage ones. You will still possibly want to alternate it to accurate the speedometer analyzing.

The T5 is prepared with an internal shifter linkage. The shifter unit is comfortably located in the perfect spot. When putting in the T5 into the older chassis, the shifter is targeted inside the shifter commencing within the tunnel. You normally don’t must alter the opening if the stock shifter unit is used. For some quick throw shifters, you can want to notch the hole for clearance.

Installing your new T5 transmission:

Now that we’re more acquainted with the T5, let us see approximately absolutely putting in one. First factor to assess is what you need to paintings with. If your automobile is already a guide transmission, you are beforehand of the game. You can reuse all your current components like the take hold of linkage, flywheel, grasp, & bell housing. Conversions from automatic or guide transmission motors will all need a brand new move member, mount, and yoke.

Manual Transmission Conversion.
Manual transmission conversions use an adapter plate that attaches to the again of your original manual bell housing. When using the adapter, depending on what bell housing you’ve got, you will want to switch 2-3 holes into your bell housing. These are clean holes and do no longer require any tapping for threads. Using the spacer will even allow you to use the manufacturing facility take hold of, fly wheel, and linkage. This makes this feature the most inexpensive manner to head.

Automatic Transmission conversion.
The T5 bell housing is a higher option. As long as you’ve got a 289, 302, or a 351w with the 6 bolt sample, the T5 bell housing will bolt without delay to the block. This option opens up a variety of alternatives. You can set your car up with the factory styled linkage or go with one of the new cable conversions. If the authentic linkage is used, you’ll want to mount a fulcrum and spacer into the housing to aid the antique styled release fork. Now if the cable conversion is used, the housings have already got the pivot mount for the overdue model release lever. The fly wheel this is wished might be a 10.Five diameter 157 teeth flywheel from Ford Racing designed for a ten.5 snatch. The Ford Racing Billet Steel fly wheel is a great choice for pre 1981 28oz balanced vehicles. You can make use of a ten.Five seize kit from a past due model application. The clutches are thinner in layout and require much less travel to disengage. The block plate, (placed between the block and the flywheel) can even want to be modified. The T5 housing relocates the starter in order that the original plate will not line up.

Once you have bolted your T5 guide transmission into area, you want to put in your move member and mount. The T5 move contributors are an clean bolt in. The 1965-sixty six model is geared up with the emergency brake bracket so there isn’t any modification wished.

Once the transmission mount and bracket are in, time to observe that driveshaft. Most packages will need to be shortened. There simply isn’t a fashionable duration. It is decided by means of the engine and rear quit. Some of the extraordinary third individuals can have an extended input and require much less to eliminate. The quality way is to get the transmission hooked up in and the automobile both on the ground or supported by the rear axel in order that it is within the herbal function. Just degree the length required and permit for approximately 1 of play at the end.

The T5 does require a different yoke. Some of the unique yokes will match into the tail shaft. As tempting as it’s miles, don’t use it. The older yokes do percentage the same spline but the T5 yoke is shorter and does not extend so deep into the tail housing. The longer yoke can harm the tail bushing via limiting the float of oil down the shaft.

Shifter Options.
What kind shifter do you need?Unlike the late version mustangs, the shifter wishes to be hooked up before it is mounted. You can’t alternate it via the floor beginning. There are many options to pick out from. The manufacturing facility shifter that the T5 comes with works pleasant but is a little sloppy for some humans. The Steeda Tri-Ax shifter is a tremendous preference and is a right away bolt on. It makes use of adjustable positive stops front and back so it is able to require you to notch the hole inside the ground for clearance. A manufacturing unit late model shift lever will work however they’re a reach to hit 5th gear. We bring a new lever that bolts to the T5 and aftermarket shifters. This lever is longer and looks exactly just like the 1965-67 4 velocity handles with the opposite lock out. These are a wonderful choice for individuals who need to hold a stock or unique look.

Another question that comes up is rear cease gear selection. Our salesman Dennis presently owns a 1965 with a five velocity as a every day driver. It changed into initially geared up with 2.79 gears. With a tire length of 225/50/15 on all 4 corners, it’d be turning around 1700 RPM @ 70 MPH. This is excellent for throughway and lengthy halls. Depending on your engine installation and energy band, changing the gears can be an excellent concept. Currently Dennis’s mustang has three.55 gears with the identical length tire. With these gears, this mustang can flip about 2400 RPM @ 70MPH. This is first-rate for all around using and is a great compromise among acceleration and mileage.

We always get the question of what oil to use. The T5 does not use fashionable equipment oil! It will harm the transmission. We recomend the usage of Dextron four. Dennis switched to the D4 and in reality noticed less difficult shifting and less friction.

Over all, I could advocate this switch to anybody who enjoys driving and crusing in there traditional mustang. It is a remarkable manner to boom the mileage and drivability of your vehicle.
