Westach 2DC3-244 Dual Temp 2" dia Gauge 100-300 f

Includes wire and connectors that fit over the pins on the gauge. Around $70.00 Make sure you order the $5.00 light kit. They already have the artwork for this gauge so it's not too expensive.

If you want seperate gauges order:

2C9-4 transmission oil temperature color bands
2C9-84 transfer case temperature
2C9-2 oil temperature (Not covered in this article.)

Note: I've been told that you can also use stock water temperature gauges and senders from AMG.

This is how the sensors come.

Assemble everything with Locktite RED or it will leak.

Transfercase Sensor

1/2" x 1/4" npt bushing

Transmission Sensor

Westach 399S1 Temp Sensor 1/8" npt 5/16" tip Around $40.00

2 feet of 3/8" transmission cooling line hose

This is a custom made 'T' manifold for the transmission temp tap. It replaces the complete stock 'T' assembly.

You can assemble your own using a 1/4" brass barstock 'T', and 3 - 1/4npt x 3/8" brass barbs. In this case order a Westach 399S8-1 Temp Sensor 1/4" npt 1" tip to fit into the T. Make sure the sensor tip does not protrude and inhibit the flow of oil.

You need 6 - 3/8" Spring Hose Clamps

Westach makes a 3/8" thru hose adapter #203-HD. It uses a 399HD sensor. This assembly can be installed in line between the existing T and the line leading to the tranmission cooler.
