TRevs, I have a manual and this section just wasn't clear. Didn't look like my transmission matched the illustrations. Anyway, I did more homework and called out the mechanic who changed my fluid last week, because that fill plug *hasn't* been removed. Turns out, he removed the torx bolt (I...

I'm confused as to which of these is the fill plug? The hex is on the driver's side, the 9/16 on the passenger side. It's a 93 YJ 4 cyl 2.5L

I just bought Redline and had it replaced. They only used 3 qrts and didn’t touched the 4th bottle but I’d read it takes 3.5 qrts. Can anyone confirm that? If so maybe I just need to add another 1/2 qrt

Aw man. So I’d have to drop the transmission to replace, and if I do that I may as well replace clutch? Not allowed to do repairs where I live so I’d have to go to a shop. Any ballpark on what I should look to pay?

All the pics/videos I’ve found to learn how to do a clutch master cylinder install look like this… Why does mine just sit in an open hole in the bell housing?

I'll try it out tomorrow. I just crawled under to look at the slave and find this... Not what I was expecting. Am I insane or isn't there supposed to be bolts and a plate to mount this to the transmission? It's just hanging there!

Yeah, 4-banger. Don't appear to be losing fluid. Pedal is not spongy. Feels like this has come on fairly suddenly (again over a month) and quickly worsening. Coincidentally, my brake master cylinder went out last year and the speed of deterioration feels the same. My brake pedal was getting...

When I got my 93 YJ a couple of years back, shifted gears real smooth. Lately (last month or so) I've noticed it starting to feel a little notchy. Figured if might be transmission fluid so replaced with Redline MT90 and noticed very *slight* improvement. Topped up brake fluid in master...

Okay, tried jumping the solenoid on the starter this morning still wouldn't turn. I swapped out the battery cable and sure enough, fired right up. Even though I seemed to be getting 12V thru the cable, I guess it couldn't handle more than that when I turned ignition. Only challenge I had was...

Okay... Changed the starter today. Wasn't that. Battery connection seems good, battery is getting 12.6v Also seems to be sending power down the cable to the starter (tested w/ multimeter) I swapped the starter relay with horn and didn't change anything. When I turn the ignition, maybe a...

Soon as the sun comes up, I'll dig into this. Thank you! If it isn't that, I plan to swap the starter. Stay tuned...

Drove my YJ for about a half hour. Parked for 20 minutes. Wouldn't start. Almost totally dead. Did a rolling start down a hill in 2nd and it fired up. Drove fine but CEL was on. Parked it at the top of another hill to turn off and restart. Same thing. Almost totally dead. This time a...

I just read that after '91 the brake switch is adjustable. There's a plunger that turns the lights on when it extends, so when I have time later I'm going to see if I can adjust it and move the plunger in slightly, so it doesn't extend as much when the pedal is at rest. Yeah, a bit disappointed...

So you don’t think it’s the pedal not returning high enough? There’s a 1/4 inch of play so if I pull the pedal back out with my toes, the lights go off. Kinda irked the mechanic doesn’t think the issue is connected to the work he just did. It’s like, dude, you just spent a day fixing the...

I just had my brakes fixed on my 1993 YJ. New booster and master cylinder, plus parking brake adjustment. I pick it up and now the brake lights stay on. If I move the pedal up slightly, they go out. Is this a fluid/pressure problem? The mechanic insists it’s not connected to the work he did...

Just fired it up to check if draining the power would help the new IAC reset... nope, no difference. I have another new IAC coming in the mail. If that makes no difference, it's gotta be a vacuum leak but absolute mystery where it's located.

I tried that and couldn’t see/hear any difference. Anyone know how long the battery should be disconnected to reset the ECU? I only had mine disconnected for the 10-20 minutes it took to swap out the IAC. Wondering if that wasn’t long enough so I’m leaving the battery disconnected overnight.

Yeah I cleaned it out thoroughly. Wondering if I should try changing the TB gasket. I bought a new one from O’Reilly when I first cleaned the TB but maybe it’s flawed. Really perplexing issue. Anyone know if replacing the TPS would impact the idle between shifts/ when cold?

I’ve read similar statements before. Why do so many IACs seem like junk? Also, did you adjust them before installing? I tried putting my old IAC back in yesterday and the tip isn’t the screw type so I pushed it in (I read it needs to be under 1 1/8 inch). Once I fired up the Jeep, the RPMs were...

I tried spraying TB cleaner around vacuum connections and no change in idle. I took it by a mechanic (who knows jeeps) and he suggested I change IAC again as the “new” one I got might be junk. This one is gold and he said get a black one. I DID keep my old one (which is black). I may clean...
