What speed did this problem happen at? the 4th to 5th grind.

 

is mitsu being dicks on replaceing trans in these cars? i was wondering if they would just do it or will they beat around the bush all day.

my 2nd gear dosent grind but sometimes i put it in gear and it dosent feel just right still drives fine but i would like to know how they stand on it.

Mine does it ever so slightly from 3rd to 4th if im shifting real quick at a high rpm
doesent happen all the time.. i suggest you engage the clutch a little longer before shifting into the gear that grinds..

 

mine works perfect under normall drivng conditions.. but @ high rpms i have the 3rd to 4th gear grind.. i beleive it is the syncro..

 

1. how would he know if the original owner never abused the car, unless you're the original owner
2.Try changing Tranny fluid, may help problem
3.Just got car back from shop after getting power steering pump fixed...maybe they raped your car while the got it worked on.
4.Dealer normally warranties syncro problems if the car is not heavily modded, 0 mods would be great.

 

I had the same problem. It is the syncro. Mine was covered under warranty thank god. goodluck

 

try changing the transmission fluid to a new good fluid. search for the kinds people like if you dont know

 

If you think just because it has 15K miles that doesn't mean it's never been abused.

 

Just got all my supporting mods together for my build up. But now i'm finding a slight grind when redline shifting into 4th . Tried everything...changed the tranny fluid, adjusted the pedal, and installed a ss clutch line which improved shifting greatly. Still grinds a llittle when i shift around 7k or higher. Now i'm trying to decide if i should delay my install & tune and do a Shep trans rebuild, or go ahead w/the turbo and enjoy it until the grinding gets really bad and rebuild it later. Any input? What all could I potentially damage in my trans if i continually drive the car like this?

 

Consider this, the exact same problem you guys are having... didn't start appearing until I passed the 170,000 mile marker in my DSM...

There's obviously a problem. And its not just the fluid. Or the way the car was driven at such low mileage. If it was a full on drag car maybe. But... also consider I shift 2000 rpm higher... than your redline... on a stock tranny... that has 8 of you guys' mileage. To me that signify's accelerated wear due to improper clearances and/or proper disengagement of the clutch. Which is a known problem throught Mitsubishi's history on the stock clutches. It might not just be the synchro's entirely. But an assortment of Mitsu's typical fu** ups.

Either way it sucks. And I find it hard to believe as hard as I drive my car its any one of these guys fault specifically.

Maybe a combination of dragging the foot, and a hardware issue. But I can't see it being solely on them if there is a TSB to support the fact.

 

correct me if im wrong but 80mph is in no way winding out fourth. just let it rev a little more you shouldnt be shifting into 5th at redline anyway unless your trying to go over 120 which isnt very smart anyway. so just rev out 4th more then you wont have to shift into 5th at a high rpm problem solved

 

mine grinds a little bit on occasion if i jam it in 4th at a high rpm

 

Let me know if u do the shep rebuild. im having the same problems again. Im prob going to do the shep rebuild.

 

i have the 4th gear and somewhat of a 5th gear grind etc...., so what a few of you are saying is if i try to take it into my local shop, they proly wont catch the problem? 03 VIII has 70k , no warranty, so im looking at having to get this replaced out of pocket?? or is this synchro issue a recall of some sort?
