This trans is a non-World Class T5. It cannot be modified for the high performance levels of the World Class models, however, it is adequate for a 258 or stock 304 to get better mileage and last longer due to lower highway RPM's. One thing to help for longevity is to avoid putting a lot of load on it when in 5th. 5th is only for cruising. Even if you're trying to push up a long uphill grade it is better to downshift and let the RPM's hum for awhile. If you want to sell, let me know!
