quickly need an answer!

so i changed my oil today....

than i drove up to boulder and back.

when i got into my parking lot i hear a grinding/rattling noise when i accelerate.

what could it be?

car has 130k miles on it

could be a headshield.

*heatshield

Where's the sound coming from? If you park, raise the hood and manually open the throttle from the engine bay do you still hear it? Does it only happen in certain gears? certain rpm range?

yeah, i shouldn't type when i'm barely awake. :rule:

its pretty much in all gears whenever it feels like but i also have a hard time downshifting

uh oh

that's not a heatshield.

when did you last flush the tranny fluid?

=\. if it helps at all before last night it would kinda vibrate a little around 3200 rpm but i just thought it was something in my dash loose. maybe that was the heatshield =]

haha I feel you. You should try typing drunk if you haven't already before.

The noise seems like the valves. But I don't know if that would affect shifting.

I heard that you shouldn't do a tranny flush unless you absolutely have to and that it's reasonable enough to just change the little amount or whatever you can get out of it every 10-15k or so to be on the safe side.

i was assuming he had a manual since he mentioned clutch and downshifting.

i've done a tranny flush before and i've had no problems

mm yeah, i'm pretty sure it's recommended something like every 60k miles (or was it 80k?).

mmhmm its a manual.

andive never had my transmission fluid flushed

you should...gotta take care of your trannyyy, speed racer

i actually think i have done it once...when i got the car..now that i think of it

if you have a manual tranny then you dont have tranny fluid.. you have gear oil.. and you dont flush manual trannys. Just drain and refill every 30K.

so it looks like i need a new tranny.


will celica gt parts fit?

7th gen Celica parts should fit. But before you go overboard and dump the tranny - drain the old oil out and run it through a filter (paper paint strainer type deal works perfectly). If you got chunks of metal in there - then you just toasted the tranny. If the oil looks OK, no chunks, refill with a good quality gear oil. If you want - try the so called "Scot Grey Mix"

The DSM guys swear by it - supposed to help problems with gritty trannys and harsh gear engagement - costs about $30. If you don't feel comfortable with that stuff - then try a good synthetic or semi-synthetic gear oil. Fluid changes can work wonders for noisy or temperamental transmissions. Not a miracle cure - will not fix mechanical problems in the transmission - but does help with noise and grinding of gears by making sure you have the right mix of grip and slip between gears.

Then check your shift linkages and bushings. Sometimes something gets jammed up in there and stiffens up those bushings. Makes the gearbox pop out of gear and hard to shift.

If that doesn't work - then you have to swap in a new tranny (if it is tranny related). But you really haven't wasted too much time pr money - just make sure you burn through other options before you $hitcan the old transmission.

very, very, helpful post.

ty for that. i actually took it to a shop xD i dont know how to do tranny stuff my self. but they are going to call me tomorrow morning.

he said the same thing about the shift linkages and bushings and said theyd fix those for free

the trans is just a drain and a fill hole... pretty simple and straight forward. i just drain my trans and diff into a low profile drain pan with a rag or cloth over the pans hole to catch particulate and inspect the fluid.

with the linkage they will probably just spray some white lithium grease or some kind of spray lubircant into the bushings, dont let them fool you.

lwell if it is that ill look at it when i get my car back. they better not take my short shifter out and say thats hwy its been fucking up >.<

it's actually really easy on a FWD. You basically just need a drain pan and one of those funnels with a straw attached to it to refill (or a pump). But getting the fill plug open is a pita sometimes because of its position in relation to the lower control arm.

dont forget people... if you ever service anything on your car. MAKE SURE YOU GET THE FILL PLUG OUT BEFORE YOU DRAIN ANY FLUIDS!!! if not, you have an empty trans, etc, with no good way to fill it.

+1
That is a great point - I personally found out the hard way on my first import after growing up working on MOPAR, GM, and FoMoCo differentials. I mean even the venerable Ford 9" rear end - had only a single plug, some earlier ones had no plugs at all.

ok so basically.

my car needs new syncs for each gear. and new forks for each gear.

or something i forget all that he said ...2470 is the total price =[

also the guy who we bought the car from said there was a new clutch on it. but the guy said the clutch is still original from the factory....

yeah umm, can i just go to burt and buy a tranny? or is it special order? my mom called the shop to figure something out shes so confusing. ._. i might see if they can put my car back together tonight so i can figure something else out

Holy smokes - all syncros and repalce the shift forks. That's pretty brutal. The price the dealer quoted you is pretty ridiculous - for that kind of money, you could go buy an identical Corolla for not that much more. Double that and get a mint condition one with less than 50K miles (according to KBB).

If the syncros are all burned up - could be a bad clutch release cylinder or it ran low on oil (pretty common, as lots of people forget to check this). As if it doesn't fully disengage the clutch and can chew up the syncos prematurely. Same deal with speed shifting or resting you hand on the shifter. Puts a great deal of stess on the syncros and burns them up pretty fast. Using a higher quality gear oil will help but easiest way it to mentally slow down the shifts. Sounds weird, but you will end up shifting faster eventually. As for the forks wearing out - that is weird. Could be those little bearings popped out of the shaft that the forks ride on. I accidentally popped some of those out when rebuilding a 5-speed and they were a PITA to get back in.
