Does it feel like the trans is downshifting? Or is it just the motor?

Stick shift. Engine RPM does not feel like its changing RPM truck speed (MPH) does not change there is no surging. Looks like indication only.

The tach may be intermittently having an issue. Clean all connections otherwise, it may need a tach
