Transmission fluid, does a manual transmission have it too?

[canfossi]

I know how to check an automatic transmission for fluid, but what about a manual transmission, do I have to check it on a manual also? Where would it be on a 1997 TJ if there is a spot to check for it? Thanks Chris

Hi,
Yes manual trannys have it, too. I don't know what a TJ is, but most vehicles have a check bolt on the side of the tranny. So you need to get under it, remove the bolt and stick your pinky in there to check the level.

Sorry, 1997 Jeep TJ, 4.0 litre. Thanks Chris

Yup. It's a good idea to change it occassionally too. The filler plug is on the right (it's where you check and fill it) and the drain plug is on the bottom. If you change it, the drain plug has a little magnet that will probably have some metal shavings on it. Wipe them off and use some thread sealer, not thread locker, before you replace the drain plug. Make sure you use the right fluid-- (75W-90 maybe??) We usually change ours every 30,000 miles or so. You'll need a hand pump to refill it.

some manual transmissions have a dipstick. check your owners manual.

note; gear oil STINKS. Dont get in anything you value.

You better check your owners manual. The manual tranny I had took regular engine oil....30W, if I remember correctly.

the transfer case on GF 99 jeep takes ATF fluid.
the transfer case on my toyota takes gear oil.

god point CF.... they better check the book.
I actually have 97 TJ book I will check and get back to you.

ok my book (may differ from your book... so check) sez

man trans takes SAE75/90 GL gear oil.
fill plug is hign onthe passangers side of the gearbox.

the transfer case takes mercon or dextron2 ATF fluid.
there is a drain plug low on the rear face, and above it a fill plug.

on both the fluild level should be at up to the bottom of the fill plugs hole.
in other words, if its full and is dribbling out of the fill hole its full.

the book says 87-99 are the same but i would find the onwers manual and double check.

Manual transmissions generally use gear oil. Automatic transmissions, (and power steering motors), operate in a completely different way, with the fluid, rather than gears, being used to transmit the driving force to the tailshaft.

Many manual transmission use Automatic Transmission Fluids and have done so for the last 15 years or so. I know that my 1/2 ton Fords have automatic transmission fluid in them. I have tractors that have hydraulic fluid as the system lubricant. My Cat uses engine oil everywhere except the final drives. Be careful and replace with what the manufacturer recommends.

Yikes, that thing must be hard to shift after sitting outside all night in -20ºF temps!

LOL! You're right I had a dodge that took 75W-90 and it was slow to warm up to say the least. You really couldn't just start it and go-- it had to run for a few minutes before it would shift.

Just as an aside: A friend, from South Africa, had damage done to the gear box of his truck when carrying a load of supplies to a camp a long, long way from any town. He repaired the gear box, which had lost all of its oil, but found that there was no oil in the cargo he was carying. However, there was a big drum of liquid soap aboard, so he used that. He kept the remainder of the drum for top-ups, and eventually sold the truck, two years later, still running with the gear box full of the liquid soap. The new owner thought that that was quite amusing, and decided to keep using the soap.
