Synchros going bad?
 

Sometimes when changing from 4th to 5th the shifter gets stuck and doesn't want to move, and when I force it it makes a loud grinding noise.

Are synchros considered wear items? I'll take it to the dealership tomorrow.

Well it's not covered by warranty if that's what your asking

Doesn't it fall under powertrain warranty though? I have powertrain warranty until 100k miles.

If you can prove that it was defective then maybe, but they will just say you abused the clutch or grinded the gears and then won't cover it

I'd leave that part out when I explain the problem to the dealer.

Does it still do it when you double-clutch? Are you trying to power shift? Or speed-shift?

Yeah and no, just normal driving. It doesn't happen all the time though, just every now and then, but today it happened when I went from 1th to 2nd, and sometimes it doesn't want to go on 1th either. I'm taking it to the dealership tomorrow because my frs has been making a rattle noise when I'm on first and under 1.5k rpms, it started after I got my TOB replaced.

^^ Sounds like something is misaligned. The clue is that it started after the tob was replaced. Hopefully that hasn't caused undue wear on other parts.

I'll ask an obvious question ....... then refer you to @Ultramaroon

Do you have a short shifter installed .. ??


humfrz

No. Everything is stock on this car.

Firs change fluid, drive for a while. Also at what rpms you are shifting?

Good point!

However, first off ...... check the fluid level to make sure the folks that installed the new TOB put oil back in the transmission........:popcorn:

***How many miles after your TOB replacement now?

Rattling noise at low RPM may or may not be normal. By itself I would say nothing wrong. Factory gear lube is super thick in an effort to keep it quiet.

If the transmission was under-filled That would make shifting more notchy and picky, especially after it gets hot.

I'm not an expert with dealer service interaction and I'm suspicious of other peoples' work. That said, If you have any intention of following up with a warranty claim, do... not... touch... anything.

2.8k-3k

The TOB was replaced 700 miles ago. I'll check the the fluids tomorrow before I take it to the dealer.

Good plan.

Keep us posted.

Do you know how, and have the tools to do that? It's not trivial.

Synchros going bad?
 

No, but I'll watch a video on youtube or something. I have nothing to do today anyways

I think he was talking about checking the transmission oil level.

What's difficult about that ... ??

:iono:

You have to stick your finger in it.

It's probably just me, but I find putting this car up on jack stands to be a pain in the ass. When I installed the exhaust recently, I had to jack the front up enough to get the stands under the hard points at their lowest level, then jack the back up, then jack the front up again to get the car raised where I could fit my fat ass up under it. I have some transmission work in my near future, and I'm honestly not looking forward to it at all. This time I'm getting my 12 ton stands I usually use for the Jeeps out of the warehouse and raising that SOB up high.

Of course it's covered under warranty. I had my transmission replaced after about 1000 miles because of a bad fifth gear syncro. 108,000 miles later it's still good.

Well, you certainly do it the hard way ....... ;)

The humfrz way is quite easy.

Simply drive the car up to the local good ol boys auto shop, give them the key and ask them to check the transmission oil level, have a cup of coffee, before you finish the coffee ..... they have checked the oil level. No charge, since I'm a regular. See how easy that is ...... :D


humfrz

They have to stick their finger in it.

You know where that finger has been?

Well, it's their pinky finger, which I doubt was "there"......:D

Besides, my transmission don't care ...... :iono:

DAMN! ......it's a good thing I quit drinken ...... if not, a large glass of vodka with a splash of bloody Mary mix would be in order ........ the music of the Wiggles, with all three granddaughters singing along, is about to drive me nuts ...... :brokenheart:


humfrz

I suggest you look up "the shocker." Or better yet, don't.

Oh, OK, ........ I looked it up ....... :eyebulge:


humfrz

2 in the pink 1 in the stink. lmao

Well, answer me this, there, DFW, did the pig squeal when you did that ........:iono:


humfrz

it was a hog, but of course

Well, that's better, good to know you Texas boys don't mess with little pigs .....:D

Is this thread going down hill ...... or WHAT!

:thumbdown:


humfrz

Now there's some post wander!

There was always the option of asking in the Tech Subs where threads (usually) go unmolested.

........and ya'll remember WHO started this "wander" thing ....... :rolleyes:


:D



humfrz

started with OP wandering about his gearbox.

Didn't want to jack your other thread.

If you looked into it and decided to pass on diy fluid check, I think it's still worth the peace of mind to pay for it. I'm guessing less than 40 bucks. Would rule out worst case.

What's that got to do with pigs ...... ??


humfrz

Mmmmm... bacon

Ahhhhh ....... I see ....... bacon > grease > oil > transmission fluid > check ..... :thumbsup:


humfrz

Damn this thread is full of ADHD...That being said, I went to the dealer complaining about a grinding noise when shifting 3-4 in high revs. They said they would replace the synchros, but not the transmission. I wonder if this will have the same positive affect as your transmission replacement.
