Pinpoint Test E: Transmission Shift Quality

WARNING: This page is about a different variant/trim than selected.

E1: DIAGNOSTIC TROUBLE CODE CHECK

Using the JLR approved diagnostic equipment, perform routine - Read DTC . Check for DTC in the following control modules:
- Transmission Control Module (TCM)
Are there DTC in the above modules?

Yes : Refer to the relevant DTC index and perform the relevant corrective actions. Perform a road test and re-assess the quality of the gear shift. If the gear shift concern is still present GO to PINPOINT TEST F .. If the gear shift concern has now been corrected return the vehicle to the customer.

No: GO to PINPOINT TEST F .
