  • My car is equipped with a 4 speed, can it be removed and a Tremec installed in it's place? I heard the bolt pattern was the same.

    Yes a Tremec 3550/TKO/TKO500/TKO600 have the same transmission bolt pattern as a toploader but with a longer input shaft. The input shaft can be shortened or a spacer plate can be added to make up the difference. Which way to go depends on the car. Cobra benfit from the shorten shaft for easier installation/removal. Mustang with consoles benfit from the spacer plate to center the shif lever in the opening.

  • What are my options for installing a five speed into an early model mustang?

    There are many different ways a five speed can be installed. There are several type of bellhousings and adapter plates to make it easy. Which bellhousing or adapter depends on which motor you have, or what type of clutch linkage is desired. See our tech alley for more details.

  • Does the drive shaft have to be shortened with installing a T-5?

    In most cases it does, the input shaft is 3/4" longer. Whether you use a T-5 bellhousing or an adapter plate, the transmission come back 3/4" of an inch. This means the drive shaft has to be shorten the same and rebalanced. Some cars, the drive shaft is ready too short and may not need to be shorten. A properly fitting drive shaft should have about 3/4" of slip yoke should be showing pass the tailshaft seal. Ready to bolt in driveshafts are available in both steel and aluminum.

  • Does a stock appearance shift lever bolt on all aftermarket shifters?

    Not all aftermarket shifters use the stock T-5 bolt pattern that the shift lever used. Shifters like the stock appearance shift lever use the stock T-5 bolt pattern so companies like PRO 5.0, Hurst, that use the stock pattern are ones to purchase.

    Top


  • Is a five speed conversion reversible?

    Yes very much so, unless you wish to install a Tremec or T-56 into a 65-68 mustang where the trans tunnel needs to be modified.

    Top


  • Can a conversion be installed and retain a stock appearance?

    Yes, very much so. The level of how stock you wish the car to appear is up to you. We have kits the use the stock linkage and OEM appearance shift lever, ball and boot.

    Top


  • Will stock crossmember work for a T-5 or Tremec?

    No, the mounting points are much different and does require a crossmember made for each transmission. See our online catolog for crossmember that are available. 1965-66 Mustangs that are convert using a Tremec can use the stock crossmember when the floor support is moved further back to help make room for the larger Tremec case. This is the reason we do not offer a 65-66 mustang Tremec crossmember. Call us for the rest of the details for this application.
