2001 4.0 5 speed dipstick?

just bought a 2001 TJ 4.0 5 speed manual transmission second hand, had no dipstick, wondering if i need a specific one for it it as i can't find a replacement online, wiki answers says it doesn't have one but the owner manual says it does, anyone clear this up for me?

Where is the dipstick on a manual transmission for a 2001 Jeep Wrangler

manual trans has no dipstick.
It has a fill and drain hole directly on the trans itself. to check you undo the fill and stick your finger inside.

Slowly add enough until the oil level is just below the fill hole. Another suggestion, change the oil in the transmission while you're there. I think it's 3qts, and if you are going to do synthetic, 10w-30 full synthetic is the same as 75w-90.

Redline MTL for synthetic or Penzoil Syncromesh for conventional in the 5 speed 2001 manual. Do NOT use motor oil in a 2001 5-speed manual trans. Search around on this forum or look in your owners manual. I've been using Syncromesh for years in my 01 5-speed with no complaints other than my first shift into 2nd on 20 degree or lower mornings takes some effort. I've been meaning to order some redline mtl online because I can't find it locally and it gets rave reviews on here.
It's easy to do, and if it's that low it's probably really old. May as well just change it and clean off the magnetic drain plug while you're there so it can collect any metal shavings. Better safe than sorry.

Don't need to drop the skid. Seriously, it takes 5 minutes.

the only faq on this i can find is Jeep NV3550 Transmission & NP231 Transfer Case Service and I assume I need the NP231 Transfer Case Service. Although at this stage it is shifting so smoothly I kinda don't want to mess with it...

It's your Jeep, it's up to you. If you wait until it shifts like crap, a change in fluids might not help. A couple of bolts scaring you off? Really? We're talking about your trans and transfer case here... When you change your oil do you say "Ah, the hell with the filter, it runs fine?" For how easy and inexpensive it is, it's worth it to know what's in there and that it's the same correct fluid. Also, on your 5-speed the magnetic drain plug is your only filter. If it's not cleaned off now and again, you're letting all those metal shards go loose on your trans. Trust me, when you see what's on that plug, you'll thank me. If you're nervous about the job, pm me you're e-mail and I'll make a short how to vid on my phone.

cool i will do it, just not today, gotta be at the airport in 5 hours and not back for 10 days, so need to buy a tub to catch the out and shifters for the bolts, i see from other pics the metal filings it collects.

although it's running fine i find it weird there is no clear indicator for engine oil, and it doesn't say anything in the owners manual, trying to download a service manual now, took it for a check up and they said they couldn't check the oil as there was no dipstick! seems pretty lazy fr mechanics i am paying...

have my girlfriends 5 speed 98 to check and compare the oil level to, but figure i will just go with a quart on that...

The gear lube level in the transmission isn't normally checked as a transmission doesn't "burn" oil like an engine can. Instead, when it is time, it is usually simply drained and refilled with the right gear lube... and your '01 requires a different gear lube in its transmission than your girlfriend's '98 does.

So basically you just remove the fill bolt, place a catch tub under the transmission, then remove the bottom drain bolt and let it drain. Replace the bottom bolt and add enough gear lube that it starts to overflow the top hole and replace the top fill bolt.

For your transmission, Royal Purple Synchromax is a good gear lube and so is Redline MTL. Or Amsoil Synchromesh. I personally would not use Pennzoil or GM Synchromesh in your particular transmission even though those two technically meet its requirements. Not everyone is happy with how their transmission shifts after using either of those last two gear lubes.

For your girlfriend's transmission, you can use either a synthetic 10W-30 engine oil or a GL-4 75W-90 gear lube like Redline MT-90. No worries, a 10W-30 engine oil and 75W-90 gear lube are essentially the same viscoscity since engine oil and gear lube viscosities are measured on two different viscosity scales.

Not recommending the Redline MTL for the 01 5-speed (NV3550) anymore?

Thanks for catching that, I added MTL above.

No problem, I was just worried that it wasn't recommended anymore. Like I said above, I have to order it. Stores around here have the Royal Purple for a ridiculous amount (usually only 1qt anyway), but plenty of Pennzoil Syncromesh.

not saying the garage didn't check the transmission oil, saying they didnt check the engine oil!

how much damage will it be doing as the engine oil reservoir seems to have been running pretty empty?

ok thanks for the help Jerry (and everyone else) after taking my laptop out and comparing to my car i can see the drain and fill holes

http://www.4x4xplor.com/images/trann...e/tranny02.jpg

i just need the tools to do it so will have to wait a week or so.

my confusion is this, if this the transmission oil/lube? I then do not have to worry about engine oil or is that another process? or is it covered in this?

never done any work on car, only on bicycles, a lot easier!

thanks again to all

confused if i need to change engine oil or transmission oil or both or is they are the same thing. i've compared the pics to my jeep and know where the drain plugs and fill points are, just need to get socket set and was thinking redline MTL 70W80 GL-4 Gear Oil looks good.

my understanding that transmission and engine oil are the same thing?

For your '01, use Redline MTL which is essentially a 70W-80 GL4 and is what they specifically make for transmissions.

Ok, I made you 3 videos. Each one shorter and shorter. When I try to e-mail them to you it keeps giving me the error that they are too long to send. I just got screwed over by Lowes and made a wasted trip there with the trailer on the Jeep so I'm kinda pissed right now. I'll try again tomorrow, if it still doesn't work I'll just put pics and descriptions on here. Evidently it's easier to do than to show...

I haven't forgot, just had to work. Tomorrow I only have an 8 hour day, I'll see what I can do. I had to create a Google account to create a YouTube account (which I had done a long time ago and no longer worked) and it still won't let me upload a 2 min video. At this point, I'm blaming my iPhone, I'll have to break down and see if I can transfer the video from my phone to PC, then to YouTube. This isn't going as easy as planned, glad you didn't need it in a hurry. Oh well, at least when it's done you'll know what to do, and I can post other videos... and read all the flaming comments.

I’m not saying anyone is wrong here so don’t jump all over this, I have a 02 with a 5 speed NV3550. I’ve had a lot of trouble with the transmission over the last year shifting and grinding. I’ve tried some of the fluids that even this thread recommends but I had no luck. I went back to the Mopar blend from the dealer. It took 2.1qts to fill, so I bought 3qts kind of pricey @ almost $20 a qt. but a week or so after I put the Mopar blend in my transmission, shifting is 10x better and no more grinding. I run Royal Purple in the rest of my rig, but I’m sticking to Mopar for the transmission. Fluids are like everything else, its personal preference.

ok back from work permit enforced holiday... think i've got the transmission fluid change down but still totally clueless on the engine oil, as it doesn't have a dipstick how do you know how much you have? i open the 'add engine oil here' cap and it looks pretty empty, but is running, pretty smooth, but i don't want to take any risks but don't want to put too much oil in, please help, this is doing my head in, checked all over the internet, normally i'm pretty good and researching stuff, but i'm at a loss...

Ok I dont know why people are only answering half of your questions. Engine oil and transmission fluid are absolutely not the same thing. As far as your dipstick, every engine has an engine oil dipstick. If its not there, its been broken off. In that case Im sure its not holding oil very well and shouldnt even be driven at all until you replace the dipstick and change the oil and filter. Just because its running smooth doesnt mean its ok. Ive seen engines run fine on very little oil, but one day they just seize up and die from piston and cylinder wall damage, among other parts.

Answered him via PM...
I made the vids, for some reason I can't upload to YouTube. Working 12 hr shifts with a 1 hr commute doesn't leave much time left over. Enough excuses though, I meant to do it with my day off yesterday but I got busy and forgot. My bad. I got caught in a rainstorm with my top and doors off on my way home. I meant to do it then cut part of my grass... Neither got done. I'll see if I can't get the problem figured out with a computer at work today.

Ok, this should help until I figure out why I'm banned from YouTube even though I've never posted anything...
This is for a 2001 4.0 I6 engine.
First pic is your engine oil dipstick. Pull it out, wipe it off with a rag, insert it back in, pull it out, look to see where the oil level is. There are 2 indications for full and low, with about a quart difference in between. If it's low, add 10w-30 motor oil (if it's below 30f outside run 5w-30). Picture is with hood raised back and resting on the windshield, passenger side.
