MIP Tranny lube?

[shane]

Guys,
I have a MIP sp1hd transmission that was on a shelfer (new, never run). I decided to take it apart to clean/lube for first time in 19years. After rebuilding, I notice the original lube ( the red stuff-looks like regular trany lube for a 1:1 car ) is a bit gummy and not at all slick. It broke down over time.
My question.
What are you guys using these days to lube your MIP transmissions? I can't find original MIP lube. Piss me off...maybe off to bst with this
Thanks for any help

I've always used a light bicycle grease on the gears and then ball diff lube for the actual diff.

Associated Stealth black grease on thrust bearings, a flea crap amount of Associated silicone Stealth lube (clear) on each diff ball (os a film of it on diff rings/plates) and absolutely ZERO grease or lube on the gears. No need for that at all, just makes a mess, attracts dirt and makes the diff heavy feeling. Nylon or plastic to metal gear mesh does not need any lubrication at all.

Thanks guys. I'll try anything. Btw, this is all metal gears.

And one should be brass. As long as you have two dissimilar materials, you won't need to lube them.

All steel.

the sp1 I had at one time used a steel top gear, steel idler, and an aluminum diff gear.

I didn't have any MIP lube for the diff, but I used a silicone diff lube(old container of ultra-lube, can't remember who makes it), and for the thrust bearing, I used the orange grease that MIP gives you with any CVD kit, I did some checking and I believe it's the same stuff.

I added a couple drops of a light mineral oil on the gears in half the case, spun the gears a bunch of times, then wiped off the excess.

All steel.

That doesn't sound right. I don't think I have ever seen an MIP with all steel gears in it. I wonder if someone replaced parts in it at some point with something that didn't belong in there.

Strange.

not that i've had many sp1's (3 at the most), but none of them had brass gears. steel topshaft, steel idler, aluminum diff gear.

I'm the original owner. This is the sp-1hd (with br-100 super pro ball diff). I always wondered why MIP would use such a thin lube for an all metal gear tranny.
I think I'm going to just put it together and put it up in b/s/t

[shane]

Let me double check that diff gear
Sorry guys, I stand corrected. Scr8p and jwscab are right, alum. diff gear, steel top, and steel idler.
I need glasses...or stop drinking

I believe Mip started offering brass idler/top shaft gears around 1989/90 when the Plus & HD diffs became available. I have several in the package, but I cannot say for certain if they ever shipped in the complete tranny kits.

I like to use this grease on metal gears,

Nice 12 year thread bump John
That Tamiya ceramic grease is the only lube I ever use on gears Good stuff.

This thread is so old that the title has a different meaning.
