"Bracket"? to solve 65-70mph vibration

I've read posts for autos but none for manuals. Where do I mount the temp probe for a manual transmission. I do not wish to use fast coolers.

Thanks,

get a PTO cover plate and have a bung welded in it to accept the temp fitting. it's not quite thick enough to get thread it, or if you can find a trans pan drain plug kit that takes a 1/8"npt drain plug, remove the pto plate, drill a hole in it for the drain plug size [like 5/8" or whatever the kit needs] and then mount your sending unit into it. .
 
Or you could invest in a pair of FASTCOOLERS like I did. Gives an extra 2 quarts of fluid and they are finned aluminum for cooling.
 
I have a probe in my pto cover just drilled and taped a 1/8" pipe thread in and have not had any leaks. Did the same with the diff covers. That said I would go with the Fast coolers as my trans can get up to 250* pulling my horse trailer on a warm day. I have a set just have not gotten them installed yet.
 
I can get it up to 190-200 empty cruising down the highway with the fastcooler. I just put them in and havent really towed anything to far yet, Just about 10,000lbs around town. we'll see how hot she can really get pretty soon.
 
I drilled a hole in my PTO cpver and welded on an 1/8" pipe fitting. Quick, easy, and you don't have to do it under the truck. Also a good chance to check the magnet on the inside of the cover ;)

You are seeing 190 - 200 in a manual transmission EMPTY?? :eek:

That doesn't make sense to me - I thought manual transmissions ran much cooler than autos... . I don't have a temp guage on my 6 speed, but did on my auto... I don't think I saw 190 - 200 on my auto unless I was stopped while still in drive or hauling something heavy. I am surprised.

I believe that this is where they run. I can see my hottest temps running down the highway for a long time at 60-70mph. Right where my 01 auto would run the coolest.
 
My 5 speed runs 180-190° on the freeway on a warm day. I haven't towed long distances yet but I imagine it'll get toasty.

Hole-ee cow. I feel like I just got hit with a 2x4 (not a truck, either)... . I had no idea manual transmission temps ran that high normally - I guess I have to put in a dang guage afterall.
 
On the 5 speed you can use a 3/4 NPT to 1/8 NPT bushing in place of the fill plug. On my 2004 6 speed, the fill plug is metric pipe with a 17 mm hex head recess. You could drill and tap the recess area for 1/8 NPT but you would have to remove the probe first each time you wanted to remove the filler plug.

is that going to work? the probe will be above the oil level so it would be reading the ambiant temp in the trans, which will be lower than the oil temp by a good deal...
 
When the gears start spinning the oil stacks up the sides of the trans housing, theres plenty of oil flow to get an acurate reading. also I think you would find that the temp of the oil and the air inside the trans is nearly the same.

Temp probe locations

Give Fabcraft metal fabrication a call. They make replacement PTO covers with a 1/8" pipe tap and a 3/4" pipe tap. They sell an entire manual transmission temperature kit but I just buy the covers and gaskets from them for about $70 and use my own gauge. I'll post their number as soon as I can find it.

On my trip this summer through the mountains of some Western States, loaded down with truck, camper, trailer, family, gear and my Samurai, we topped out at around 17K, and the transmission temps never exceeded 210.

They do tend to get hotter at a faster highway speed. But pulling through slow winding mountain roads, it stayed under that mark.

Drive ithard and fast, and it'll heat up to 190 fairly quick.
