Can I use an oil temperature gauge instead of a trans temp gauge in my P/U to monitor the T400's temperature? The trans temp gauge goes to 280 degrees, while the oil temp gauge goes to 300 degrees. I'll have to have a bung TIG'ed into the trans pan (pan is made of aluminim) for a sender... what else should I be considering?

Yes, you can use it. Trans temp Gauges come with several Max degree ranges, up to 250*-400*.
You could also use a Tee fitting in the Cooler return line for Temp reading.

What kind of trans? Some come with a port that's blocked off, that you can easily unblock.

I just tapped my aluminum pan and used the smallest brass adapter with thread locker.



The BIG picture.

Thank SSedan 64 for the redirection to the Summit sight.

EOD Guy: It's a Turbo 400 that came with a factory installed deep [sheetmetal] pan. I think it may have been out of a 3/4 or 1 ton truck, but not sure. I picked up a NIB, B&M deep, finned aluminum pan on Craigs for $50 and am planning on using it. I live in the Phoenix-metro area. July /August temps are regularly in the 110-115 degree range... which probably equates to 125/130 or more coming off the tarmac. I'm thinking about a seperate trans cooler with a small fan for those "extra-warm" days.

malc: Nice clean install job. What I was wondering was, where is your exhaust? I see the tube ahead of the oil pan... is that a crossover pipe? My vision isn't as good as it used to be, but you seem to have the cleanest tuck job on your exhaust I've ever seen. Tell me where you hid it !

TH400 didn't have a extra bung for a temp sender..... If you're going to use the B&M..... now would be a good time to install a fitting..... If you have a welding shop, they could weld a bung to the side very easy, if not I have used a brass fitting that was threaded into the pan and a brass coupler, cut off like a nut, securing it from the other side, with JB weld sealing everything permanently

If you don't want to drill the pan you could also use a fitting that goes inline in one of the cooler lines. Several companies (e.g., B&M) sell them to go with their gauges. I assume you want to measure the temps in the line going out to the cooler.

I have Hedman Hedders 21/2" to 3" Flowmaster and here´s how it goes,
before paint and pre aluminum trans pan.
