The housing must be placed in the correct orientation for the particular driven gear being used. The driven gear housings go in the tailhousing assembly on all two-wheel drive applications. Notes: All Torqueflite transmissions use a 1.75" diameter driven gear housing. Torqueflite Speedometer Gears Drive Gears One fits gears from 34 - 39 teeth and the second one fits gears from 40 - 45 teeth.
Notes: - Two 2.078" diameter housings, each made from either aluminum or plastic, are available for driven gears with 34 or more teeth. * - This gear is shipped in all TCI Street Fighter 700-R4 transmissions. * - This gear is shipped in all TCI® StreetFighter® TH400 transmissions. The driven gear housings go in the case just forward of the tailhousing. Notes: Two aluminum housings are available for driven gears with 34 or more teeth. Two housings, each made from either aluminum or plastic, are available for driven gears with 34 or more teeth. Notes: Chevrolet transmissions use a 1" diameter steel driven gear housing located in the tailhousing on all two-wheel drive applications.īuick, Oldsmobile & Pontiac transmissions use a 2.078" diameter driven gear housing. * - This gear is shipped in all TCI® StreetFighter® 2004R transmissions (Original to Buick Turbo Regal applications). The gear can be replaced separately by removing the retainer clip on the governor shaft. The drive gear is part of the governor assembly which is located inside the oil pan. Notes: - All 2004R transmissions use a 1" diameter steel driven gear housing. Speedometer gears: 2004R | TH350 | TH400 | 700R4 | Torqueflite | Ford # of Drive Teeth: Axle Ratio: Tire Diameter:Įnter the tire width in millimeters, the aspect ratio, the wheel diameter in inches, and If you don't know your tire diameter, calculate it below using the P-metric sidewall designation. Use the following formula to calculate the Tire Rev. Be aware that some transmissions will have different driven gear housings depending on the tooth count of the driven gear. The driven gear is located in a removable housing usually in the tailhousing of the transmission. Note: Drive gear refers to the gear that is on the transmission output shaft. TCI® now stocks the most popular speedometer gears. The accompanying charts show what gears were manufactured for each type transmission. The following formula will work for any GM, Ford or Chrysler vehicle and is very useful when there is no established baseline from which to work from such as replacing a transmission in a vehicle that was purchased without a drive line.
