Off Subject: THM400 Oil Temp Question...

[Dennis C.]

...On my Carvette, B&M Electric Trans Temp Gauge indicates about 100* after quite a few miles of normal warm up. So, should I be concerned it's too low, or should I be a happy camper and just wear a happy face...??? TIA, Dennis

Sounds good to me! 100deg. is pretty cool for an autobox to run. Normal temps are closer to 180-200F, but...cooler is always better for a trans. Ya sure the gauge is accurate?!

Be happy! The cooler it runs the longer it will last, but it should be the same and more then your engine temp.

I'd check the gauging system for accuracy. All THM-400 used a transmission oil cooler of one sort or another, but I don't think that very many, if any, would run as low as 100 degrees under normal operating conditions and ambient temps.

By the way, you're not necessarily "off-subject". Quite a few Corvettes originally used THM-400 transmissions which was one of the best transmissions ever installed in a GM car. It was so good that after, essentially, discontinuing it in the 80's, GM brought it back and, even later, updated it to electronic control.

put the temp sender bulb in a coffee can

of boiling water and the gauge should read close to 200/210 degrees. NEVER use your better halves good pots or pans for this test! do not ask how i know this

Clem, Would that be like when I...

...baked a pair of painted exhaust manifolds in my wife's new Thermador oven?

Or when I used my wife's dishwasher

to clean a really nasty, flea market bell housing? I washed it twice and then ran the dishwasher twice with nothing in it to clean the dirt and grease. I don't believe that I have mentioned this yet to her.

Gary
btw, I highly recommend dishwashers to clean parts, provided you have spousal approval. Worked like a champ.

Re: Or when I used my wife's dishwasher

Oh, that? For that, I use the regular dish washer. The regular dish washer has been doing the dishes for a few years now and she does a pretty good job.
