for about the last 1000 miles or so, I started to notice that it's getting difficult to get my car into gear. It no longer shifts smoothly into 1,2,3,4 or 5. I thought it was the tranny fluid ( I have 29000 miles) so I put in some Mobile 1 75w90. It felt a little better for about 2 days and it just seems to be getting worse.

Also, First gear tends to "pop" out if I accellerate fast.... when I go to shift into second, I hardly have to touch the shifter to get it out of first.

Any thoughts on what this could be?

Synchros?

I did misshift about 5k miles ago, but I caught it quick and only went up to about 7250-7500 for a split second.

Could I have screwed up the synchros?
Is it time for a new tranny? ( I hope not)
Could it be because of the clutch?

Thanks,

I would take it to the dealer if you are still covered.

Does the an aftermarket S/C Pulley void the transmission warranty?

peteyd

no the pulley only voids the s/c warrenty.

It sounds like your shifter cables got knocked out of whack. I'd look into tightening and realigning them before you take it to the dealer, since they're going to find a way to charge you money.

I can't see your mods from this window... Do you have a short shifter installed? Did you do the S/C installation? (it's right over the tranny) Bounce on something really hard, or bottom out ?

It could be as simple as a 15-minute fix.... if you had a REAL tranny problem, it wouldn't go into gear at all. It isn't your clutch.. a clutch problem would prevent power transfer to the wheels, not what you're experiencing.

hopefullly its not a shift fork...had an s-10 break one..it would throw the shifter at ya!!...

sounds simple though......so just worry about the bad later

put it in 5th gear and press the gass. if the RPMs go up and you don't move, time for new clutch.

I have a similar problem. You shift slow, and it goes into gear just fine. But hammer it, and try to shift like your racing, and you grind right? No one has really gotten down to looken yet, as it takes some money good money to pull the tranny apart and check out your synchros. The synchros themselves don't cost much, but the installation will. I would double check your tranny fluid as well. I think I'm going to go with some of the RedLine tranny fluid to see if that smooths things out some.

PS...this dosen't happen if you drive normal like your suppose to, and not racing all the time while powershifting through the gears every weekend...lol

yea dude i have prolly have 21k mi on mmy car but i bout it with 15k.. and prolly around 18k it does the same thing ur does.. when i mash on it it like pops out of 1st and almost goes into 2nd.. like u said i bearly have to touch it

rhythmnsmoke

I have popped out of 3rd before. It didn't start doing it till recently. I don't know if I want to pay to have it pulled apart ($500+), or just say screw it, keep racing, and tell ZPI to float me that 6spd tranny when they get done with it.


PS....we have about 18k+ miles. And have been boosted + racing every weekend for probably 7k+ of those 18.

if you look at where your s/c bolts to the tranny right by your radiator hose in that little gap see if your s/c mount broke off your tranny because they have a tendency to do that ive seen it happen

As stated, I think the shifter cable alignment is off from the installation of the TRD quickshifter.

And i couldn't see the mod list from the "post reply" section... but i guess i pretty much called it anyway

I don't the the Mobil 1 trany fluid is specified for our trany. Don't think it's GL-4 compatible. Might want to drain that soon after you figure out what the shifting throw problem is.

dachmo

OK everyone... I drained the tranny today and filled it up with some Redline MT-90. The shifter goes in like butta... lol

Nice and smooth. I think the Mobile 1 was making it worse ^^^

funny because that's what they gave me at Pep Boys. They looked up the car and said "that's what you need"

Thanks for the input... I'll kepp you posted if it gets bad again

Eh, Mobil 1 is over rated. The are not known for their trany fluid. Their oil could be abused on here too, but this one's about trany fluid. Always seems to have a noiser output when that trany fluid is used.

MT-90 is what I have and it's great.

How do i drain my tranny fluid? i can't even find the drain.

What's the verdict on Royal Purple Tranny fluid. Do you think it's as good as the Redline stuff?

web

Possibly, but I know their oil has a graphite powder in it that eventually begins to scar cylinder walls and pistons. Not sure about their trany fluid but I'm sure it's around the same make up. MT-90 seems to be the best pic through all the forums I've searched and I'm really happy with how it feels in mine. I have a short throw so it did tighten up a bit, but still very smooth in comparison to stock throws.
