## NHTSA's summary

Technical Bulletin \(ECM, TCM Software Update and Valve Body Replacement for Harsh Up \- Down Shift from Transmission when Cold\): Customer may experience harsh up shift in gears 1\-2 and 2\-3, or harsh down shift in gears 3\-2 and 2\-1. The symptom is most noticeable at transmission temperatures below 60°C \(140°F\). The production solution for this issue was an updated transmission valve body, ECM and TCM software. The updated ECM and TCM software and updated transmission valve body addresses: ? Harsh Up/Down Shift 1\-2\-3, 3\-2\-1. This document discusses the "Fault Codes" necessary to diagnosis, and potential remedy of the issue. The fault codes for checking warranty coverage for servicing the vehicle are also available.

- [TT131301a](/bulletins/10238941.md), 2023-07-10, Service bulletin: POWER TRAIN; ENGINE AND ENGINE COOLING. When servicing the timing chain sprocket or removing the vibration damper, be aware that one bolt holds both the vibration damper \(harmonic balancer\) and the crankshaft timing chain sprocket to the crankshaft. Once the damper is removed, the crankshaft should not be rotated unless special tool spacer T10368 has been installed. The crankshaft timing chain sprocket and spur gear drive on the crankshaft have a coupling that must be seated correctly during assembly. Failure to install special tool spacer T10368 before rotating engine will cause the engine to skip time and bend valves.

- [TT011401a](/bulletins/10238938.md), 2023-07-10, Service bulletin: POWER TRAIN; ENGINE AND ENGINE COOLING. Install a vacuum gauge on the dipstick tube and check crankcase vacuum at idle. Compare to a known good vehicle. If the vacuum reading is lower than the comparison vehicle, visually inspect for oil leaks between the engine and the transmission. Smoke test the crankcase by connecting the EVAP smoke machine to the dipstick tube and inspect for leaks at the rear main seal \(this will limit pressure to 2 PSI\). DO NOT apply shop air to the dipstick tube or the crankcase. If a rear main seal leak is identified, replace the seal. Once replaced, recheck crankcase vacuum at idle. If low, check for additional oil leaks and verify crankcase breather operation \(repairing as necessary\). Erase the faults and road test 10 miles to recheck operation.

- [TT321401](/bulletins/10238600.md), 2023-07-05, Service bulletin: POWER TRAIN. Incorrect torque converter or flywheel/flexplate installation can result in transmission damage. When installing an engine, flywheel or transmission, please follow the installation procedures outlined in ELSA. For the flywheel/flexplate, please be certain the correct shim is installed between it and the crankshaft \(reference VWIQ120\). When installing a torque converter, press the torque converter hub through the seal as far as the first stop. Turn the torque converter while pushing toward the transmission using light force, until the cut outs in the torque converter hub lock into the pump wheel plate. The torque converter slides in. The torque converter is installed correctly if it is easy to turn by hand and if it fits evenly in the transmission bell housing. Additionally, it should spin freely when the transmission bell housing bolts are torqued to the engine block, prior to installation of the flywheel to converter bolts \(reference VWIQ121\).
