Hello.

In my experience when the transmission gearshift indicator is not visible after reprogramming it may be necessary to program the transmission controller separately. The tolerance for the distributor setting is very small. If the distributor is set incorrectly the engine may run well but you will get code 1345. We have Launch X451 scanner but that tool does not help us set the distributor timing. We need to use an older Snap-On tool for the job.
