Explain the key functional and operational differences between a conventional continuously variable transmissions
(CVT) and torque converter and the units fitted to hybrid electric vehicles. In your answer, briefly describe how a CVT transmission operates in the hybrid vehicle. (100 - 150 words)
briefly define the following:
1. airborne transmission
2. common vehicle transmission
3. contact transmission
An electronically controlled transmission has erratic shifting: Technician A says that a poor PCM ground will cause this problem. Technician B says that a bad AC generator-to-battery circuit will cause erratic performance of a transmission or transaxle. Who is correct?
