Borg Warner, the designer and original manufacturer of T-5's, classified the five speed manual as a "light duty" transmission. In 1997, Tremec acquired the rights to manufacture transmissions for U.S. auto makers by purchasing Borg Warner's Automotive Gear Divison. Over the years the T-5 has been used as factory equipment in many cars, light trucks and SUV's by automotive manufacturers world wide. From 1987-1993 the "World Class" T-5 was factory equipment in 5.0L Mustangs. The World Class T-5 is known for being a smooth shifting, strong, yet light weight transmission that best suited for daily driving and occasional racing. However, when the horsepower (and torque) is turned up, or when heavily drag raced, the T-5 can "grenade" quickly. That was the fate of the T-5 transmission that ATF customer Rich Colas brought to ATF. As ATF's owner Jason Gatlin rebuilt this World Class T-5 transmission he added some upgrades that will allow Rich to get more out of it without breaking the transmission or breaking the bank. The T-5 received an upgraded cluster and gear set, carbon fiber syncros, billet cluster support plate and a steel throw out bearing retainer. As with any ATF complete rebuild, all of the tranmission's "soft parts" (bearings, races, shift fork pads, o-rings, etc.) are replaced with top shelf components. ATF does not mass produce units. Every transmission is custom assembled, one at a time, to ensure the highest quality and longevity. There are many different combinations available for ATF's T-5 transmissions. Contact ATF more information about what's right for your application. ATF services and builds automatic and manual transmissions for all makes and models of cars, trucks, vans and SUV's (domestic and foreign). This is how the transmission arrived to ATF's Davie, Florida shop. We set the pieces out on one of our workbenches to examine them. Third gear failed which is common when drag racing a T-5 transmission. A typical World Class T-5 is rated at around 300 ft. lbs. of torque. When they are taken past that point, they are living on borrowed time... especially when drag racing 
3rd gear failed filling the transmission with debris. 
ATF's owner, Jason Gatlin disassembled the transmission...starting with the 5th gear shift fork...(Note: We're starting here because this transmission was dropped off in pieces.) 
Then 5th gear is removed... 
Removing the cluster bearing retainer... 
Removing the mainshaft and gears... 
With the mainshaft out of the way, we can get a better view of the cluster. 
The cluster removed... 3rd gear is wiped out. 
Disassembling the main shaft... 
...the main shaft was disassembled. This photo shows all of the old parts that will be replaced. 
The fiber parts of the new syncros being presoaked in automatic transmission fluid... 
All of the new parts laid out on the bench... 
The T-5's case and its new parts being cleaned in the parts washer... 
Everything laid out on the bench ready for assembly...  Jason begins by installing the tapered bearing onto the cluster... 
...then the input shaft's tapered bearing is installed. 
New needle bearings are then installed in the inside of the input shaft... 
...followed by a roller bearing. Special transmission building grease is used to ensure the needles and bearings are well lubed. 
Then the input shaft is test fit to the main shaft... 
The main shaft is ready for it's gears and syncros... 
A new bearing race and inside seal was installed. Then silicone sealer was applied to the outside sealing surface of the new steel throw out bearing retainer. 
The new steel throw out bearing is installed. 
For the finishing touch, Jason installs a Steeda Tri-Ax shifter. 
Completed. Rich is back on the road with his fresh ATF built T-5. He reports perfect shifting and performance.
