faulty transmission temp. reading

[pattypape]

Hey,Let me try an answer,

We are in our second year of ownership, Maybe we are sophomores??
We have learned a little about our 88 FC.
This suggestion may help and contribute for our many silly first
year questions.


I am not an expert gage person, But we ordered a Teleflex oil
temp gage from BlueBird. After replacing the gage the
temp read 250/ 300 degrees.
In talking to Teleflex, we discovered that the original gage
is no longer available. The replacement gage also requires
the replacement of the temp sensor probe, to match the latest gage.
The original BB gage and the replacement gage carry the same BB part
number, but it was not the same gage. After replacing the defective
gage and later the sensor all readings are normal.

If you want a part number, I can dig it up from the pile of
notes and receipts, we have collected.
