TH400 info
 

have a TH400 in my 67 c10 2wd w/350, want to add a trans temp and pressure gauge and not sure where to look for proper access to add a fitting. Is the cooler line ok or somewhere else on trans case.

Re: TH400 info
 

In the past, I've welded a bung in the pan for a temp gauge. You just have to be sure there is no interference issues.

thanks for the reply, i was thinking about putting a tee fitting in the cooler line to the radiator, the temp sensor is a 3/8" thread and not too long, try different
fittings to keep the sensor not too much in the flow, not sure if this will be OK
for good temp readings.

My B&M trans temp gauge came with the fitting for the cooling line. It was very simple.

thanks for the info, i'll look it up, next on the list is a good transmission rebuilder

Re: TH400 info
 

If you put the sender in the cooling line, make sure it is in the line coming from the trans and not going back to the trans.

will do, thanks , think the top line is out, waiting for parts to get here from mail order
Jegs, using their led gauges etc.
