Checks, in order
- Check the calibrationAsk the dealer to confirm the TCM is on the latest calibration and whether the two 2022 bulletins and recall 24V125 have been applied. Reflashes are free under warranty or the recall.easy $ · under about $50
- Separate transmission from drivelineA clunk that happens when you shift from Park to Drive or at the first tip-in is often driveline lash. On 2022 trucks, recall 22V445 covered rear axle flange nuts that loosen; a clunk plus a vibration or a wet hub needs the axle checked.easy $ · under about $50
- Harsh first shift of the dayOwners report a firm 1–2 on the first drive and a 2–1 clunk coming to a stop, mostly cold, after the reflashes. Document it with dates and temperatures; Toyota has continued to issue software updates for the 10-speed, and a dealer can check for newer ones.easy $ · under about $50
- FluidThe 10-speed uses Toyota WS and is checked at temperature through an overflow plug. A leak at the extension housing on 2WD trucks was covered by tech tip T-TT-0679-21. Low fluid will cause flare and harsh shifts no software fixes.medium $ · under about $50
Applies to: 3rd generation Tundra, 2022 on, with the 3.4L twin-turbo V35A-FTS V6 and the 10-speed automatic, including the i-FORCE MAX hybrid. Most items are covered by Toyota's 3 year/36,000 mile basic and 5 year/60,000 mile powertrain warranties or by an open recall, so the first check on this truck is usually a VIN lookup.
