Does it have a filter somewhere? Does it get hot? Does it have a transmission cooler? Thanks for helping out a rookie. It's wierd that I know how an automatic works and don't have much of an idea about a manual.

 

round and round...
filter is in the pan...yeah, it can get real hot...cooler is in the radiator....they're engineerd by aliens....it's good to add a cooler if you tow a lot.

 

I think he's talking manual transmissions, which basically sling fluid.Manuals can get hot, but generally not as much heat buildup as an auto due to hydraulic pressure and friction which produces heat in an auto.

 

No filter. Most have a magnet.
Yes, it gets hot, especially when you have a heavy load on it in a gear other than direct drive. (5th on a 6 speed)
No transmission cooler. This is why synthetics are important in manual transmissions and rear end gears. The synthetic oils don't break down as quickly under the high heat that is generated in a transmission or rear end operating under a heavy load.

The lower shaft in the trans is sitting in the oil, so when the truck is moving or the trans is in neutral with the clutch engaged oil is being slung all over the inside of the transmission by the rotating gears.

 

That is what I had thought, well, actually, never really thought that much about it before. I should say that was my understanding. It would seem to me that they would want some type of filter, but I guess that the magnet is supposed to take care of any shavings.

Another question is this -- what is the danger of them putting a little too much fluid in it? The reason that I ask is this -- the four bolts at the top of my shift tower were a little loose and leaked some fluid. The local mechanic said no problem, was just a little low, did not leak much. He said that he has seen this more than once. He did some work from inside the cab and added a little of synchromesh through the top. Now I wonder if he added too much? My dealer is too far to drive to just check the fluid level. I guess that I will check the fluid level myself and if he put too much in I will just let what runs out the hole run out.

 

Oh, thanks everyone for the info.

 

The only danger to overfilling is that the "extra" might leak out. On the old Getrags in the 1st gen trucks it's common practice to overfill them by a quart to make sure the input bearing gets well lubed. That's a weak spot on that particular trans, I'm not suggesting you do that to your truck.
