Transmission Pressure gauges

[Mark Glaubke]

I purchased your transmission gauges 400psi and 400psi sending units and installed. I attached the white wire from the gauge panel to sending terminal on gauge. I used the white and black wire from the engine wiring harness to the sending unit. On engine start up the gauge goes to like 350 not in gear. HELP

Rob my idle is 650. the pressure goes up to about 350lbs not in gear

[Rob Schepis]

What’s your idle at? The tranny pressure is idle speed sensitive.

zf 220a 1.5 to 1 not in gear its at like 350

[Rob Schepis]

What exact gear? ZF?
Sounds normal to me. It should just drop out momentarily when shifting between F-N-R
