Your new B&M transmission oil temperature gauge will
accurately monitor transmission oil temperature and
warn you before excessive heat ruins transmission uid
or causes damage. High heat conditions are destructive
of both transmission friction materials and transmission
components. Transmission operation in the normal op-
erating range of 150°F to 250°F will ensure long life and
dependable service. This gauge will work with all 12 volt
negative ground electrical systems.
STEP 1. Disconnect positive terminal battery cable to
prevent accidental shorts and/or damage. Mount tem-
perature gauge.
Mounting panel: Install panel in position and secure using
the two sheet metal screws supplied with the kit.
Dashboard or console: Drill 2-1/16" hole into surface
you wish to mount the gauge in.
Gauge pod: Gauge will t into 2-1/16" gauge pod hole.
Position gauge in mounting hole. Install mounting bracket,
nuts and lock washers in position. (See Fig. 1) Install one
brass at washer, one lock washer and one nut on each stud.

Rotate gauge until it is properly aligned and tighten each
nut nger tight.
STEP 2. Locate the oil return line to the transmission. On
Chrysler and most Ford transmissions, this is the line to
the rear of the transmission case. On GM TH-350, TH-
400, TH-700R4, and Powerglide transmissions, this is the
upper oil line to the transmission case. On GM TH-200,
TH-200R4, 4L80E and Ford AOD transmissions, this is the
lower oil line to the transmission case. Note: This loca-
tion is recommended to monitor the true transmission
temperature going in, as well as checking the oil cooler
efciency. Cut the steel tube oil line in a convenient loca-
tion using a tubing cutter or hacksaw. Carefully deburr the
ends of the tubing. Select the proper T-tting and tighten
the compression nuts securely. Be sure to double-check
T-tting holes are bored through all the way.
STEP 3. Place a small amount of sealer on the threads of
the T-tting, install the proper coupler and tighten secure-
ly. Place a small amount of sealer on the threads of the
temperature gauge sender unit. Install the sender unit into
