SM465 Trans Temp Gauge

[estrugo]

Hi,

I found a lot of info on automatic trannys and how to install the trans temp sender, but nothing on a manual SM465

I have an Autometer Pro Comp gauge that is still not installed (it's on the dash, but not connected yet)

I saw in the transmission that there is an oil filler plug and an oil drain plug, is it OK if I install the sender in the Oil filler plug? of course I will have to find the way to change oil from the drain plug when needed...

Any advice?

I have no knowledge of these things first hand but you'd probably be best off getting an aftermarket PTO cover and drill/tapping a port into it. You could call up DIY4X and talk to Kert, he's pretty helpful with pretty much everything and could likely hook you up with a modified pto port cover. And his new aluminum covers are cool looking as a bonus!

If you use the fill hole you'll have to overfill the trans for the probe to be covered in oil otherwise the oil will be just below it.

Use an aftermarket PTO cover as suggested.

Or just braze a pipe coupling on your stock steel PTO cover. Not sure how hot they run, so not sure what temp gauge you would need.

This is pretty unnecessary. Any condition in which the transmission is overheating is going to be a product of something already being terribly wrong. Or water in the thing, in which case just vent and seal it properly...

I've always been curious as to how hot they get under certain conditions...cold they tend to be hard to get into gear, but once warmed up, no issue.

Additionally, when climbing long grades in lower gears for long periods of time, I've occasionally gotten a whif of gear oil, I think it would be interesting from a technical standpoint to see the temp range.

Don't doubt it's unnecessary under almost all conditions. Running a temp sender in the drain plug location temporarily would be the no-brainer, assuming temporary use didn't involve beating the rig up on rocks or going over other obstacles that could break it.

I know a guy that wanted a temp on his zf5 ford trans, and I thought that it was not needed. Towing temps were as high and higher than an auto would have been in that pickup. 200 deg plus. I would have to ask him, but it seems like I remember him saying 260 deg plus under certain conditions worked hard.

I'll probably add one to my nv4500 because I like gauges and it's a 2wd which I'll be hauling with. If I do go this route I'll definitely put it on a pto cover, I was going to get 2 of the diy aluminum ones to help act as heat sinks.

were I work now we run a lot of gmc5500 top kick rollback tow trucks .

few years ago when scrap was high in price the local junk yard had us pulling cars/trucks left / right .

1 day mid 90* degrees out the 1 guy come in and said he smelled gear oil in rear . found factory synthetic oil with under 60k miles was smoked .

if your thinking its getting hot or will get hot add a gauge . it could save you $$$ in the end.

Thats surprising. But I guess the real question is, what good is it going to do you? Theres no cooler to upgrade, yeah I guess you could put a finned cover on the side of it, but whats it going to be there for? O **** theres something wrong already causing this thing to over heat?


Now what would be trick is a cover with a sump and a recirculater pump setup to a small cooler. I dont know why but I guess if you're going to monitor it you might as well be able to do something about it other than pull over if it gets too hot.

It's an SM465, it's unnecessary.

I said that already...

I was going to say that in my previous post but figured it was a stupid idea. If that much heat is being created though, I would need a bigger transmission.
