3rd Gear 33034-36100 For Toyota Coaster — Genuine OEM 33T-37T Transmission Gear
Product Overview

The 3rd Gear with OEM reference number 33034-36100 is a verified direct-fit replacement for the Toyota Coaster minibus equipped with manual transmission (MTM). This gear is a critical component of the transmission system, responsible for transferring power from the input shaft to the output shaft at the 3rd gear ratio.

The gear features a 33-tooth configuration on one side and 37-tooth on the other (33T-37T), designed to mesh precisely with mating gears within the transmission assembly. A worn or damaged 3rd gear can lead to gear skipping, difficulty engaging 3rd gear, unusual grinding noises during shifting, and compromised driving performance. This OE-spec replacement gear restores proper transmission function and smooth gear engagement.

Manufactured to meet or exceed original equipment standards, this gear is produced from high-strength alloy steel with precision-machined teeth for reliable power transfer and long service life under demanding commercial operating conditions.

When to Replace:

  • Gear skipping or jumping out of 3rd gear
  • Difficulty engaging 3rd gear
  • Grinding noise during 3rd gear shifts
  • Visible wear or damage to gear teeth
  • During complete transmission overhaul

Installation Guidelines (Reference Toyota workshop manual for complete steps):

  1. Safety first — securely support the vehicle
  2. Remove the transmission from the vehicle
  3. Disassemble the transmission case following manufacturer sequence
  4. Remove the old 3rd gear — note the position of bearings, synchronizers, and related components
  5. Compare the new gear with the old unit — verify part number (33034-36100) and tooth count (33T-37T) match
  6. Inspect all bearings, synchronizers, and shafts for wear — replace as needed
  7. Install the new 3rd gear with appropriate bearings and synchronizers
  8. Reassemble the transmission following manufacturer sequence
  9. Refill with the correct transmission fluid
  10. Road test — verify smooth shifting in all gears
Pro Tips:
  • When replacing a single gear, inspect all related components (bearings, synchronizers, shafts) for wear
  • Replace the needle roller bearing (90364-XXXX series) simultaneously for 3rd gear
  • Always use OEM or OEM-grade replacement parts for critical transmission components
  • Consider a full transmission rebuild kit for comprehensive repair
