I thought you were only supposed to put transmission fluid in transmissions. Is motor oil (the non-slippery stuff) REALLY OK for transmissions? What about automatic transmission? If it is OK, I could have used this information a while ago, I had a beater which got about 150 miles/quart of TRANSMISSION fluid. (!) I could have used el cheapo motor oil? The transmission worked fine (until it ran low on fluid) it just leaked. (The car is currently getting another one) "There's a madness to my method" Mike Moroney ..!decvax!decwrl!rhea!jon!moroney

> Huh? I thought you were only supposed to put transmission fluid in > transmissions. Is motor oil (the non-slippery stuff) REALLY OK for > transmissions? Read the article again. He said (and I will confirm this, being a Honda owner also) that Honda manual transmissions take motor oil. No statement was made concerning transmissions in general. Try reading your owner's manual. And don't assume that all cars are the same.

> Huh? I thought you were only supposed to put transmission fluid in > transmissions. Is motor oil (the non-slippery stuff) REALLY OK for > transmissions? You must be talking about ATF (Automatic Transmission Fluid). As those of us who have worked on manual-trans cars know, REAL transmissions use oil. However, the transmission oil should normally be considerably heavier grade than the standard motor oil. (Which is why it's sort of hard to shift when you start the car on a cold winter morning...) \tom watmath!watdcsu!haapanen

I can only speak for HONDA manual transmissions. They take motor oil. I would guess that engine oil would demolish an automatic ... -- E.

Some cars do use motor oil in the transmission/differential.
I had a 77 Honda Civic that called for 10-30 oil in the
trans. I put some syntheticc oil in hoping to reduce wear, etc.
The transmission became hard to shift and the gears would grind,
especially between first and second. I put standard 10-30
back in and the problem went away. Turns out some friction is
required to make the synchro rings work properly. The synthetic
oil reduced friction to a point where the rings did not work.

Yes, REAL transmissions use oil. ( I must confess that I never do think about automatics when talking about transmissions...) For some obscure reason, the ****** HONDA ****** takes 10W-40 motor oil in the tranny. For most cars with real transmissions the grade in 90w. Not so for HONDA. In any *MANUAL* transmission watch out for slippery oil. (Come to think of it, my old Honda motorcycle used 10w-40 in the tranny also... I wonder if this is a trait of motorcycles that Honda caried over into cars ... hmmm) -- E. Michael Smith ...!{hplabs,ihnp4,amd,nsc}!amdahl!ems No one would dare claim these opinions.

Yes indeed. My '85 Accord manual says to put 10W-30 in the transmission (manual of course). No mention of transmission oil. On the other hand, my '82 Sentra requires 80W-90 transmission oil - real viscous stuff. Shifting into 1st is difficult when the Sentra is cold, fine in the Accord. Seems to make things easier if you can use motor oil. Either way, use what the manual says if you don't want to break it! gbgb aka the longjmp artist
dss00@amdahl.UUCP (Deepak S. Sabnis) (12/11/84)
According to Chilton's Easy Car Care, manual transmissions
are lubricated by motor oil or gear oil (a heavier cousin of
petroleum based oils). It varies from manufacturer to manufacturer.
Chilton's book reccomends looking up owner's manual to make sure.
The automatic transmissions on the hand need special stuff called
automatic transmission fluid (ATF) which also comes in more than one
variety.

MGB's have long used standard engine oil in the transmission!!bprice@bmcg.UUCP (12/20/84)

In both the manual tranny (MG 1100) and the automatic (Austin America), the tranny was in the oil pan. Thus, the engine, tranny, and differential all used the same oil, the same oil pump, the same oil filter. Maybe I should discuss these cars (I had one of each) under the "My car is slower than yours" subject. -- --Bill Price uucp: {decvax!ucbvax philabs}!sdcsvax!bmcg!bprice arpa:? sdcsvax!bmcg!bprice@nosc
