I drive a 03 CL Type-s 6 speed manual.
When I try to shift into 3rd from any gear, there is a grinding noise and the stick vibrates violently. This only happens with the 3rd gear and all other gears are fine. Is this problem fixable or will I have to replace the whole transmission.

 

try topping up/changing your transmission fluid?

 

bent link maybe?

a friend of mine had 91 CRX (beater car) and it started doing that, but his was going into 2nd gear and 5th gear.

 

worn/damaged 3rd gear and syncro

the 2 gears that fail most of the times are 2nd and 3rd gear (mostly because of hard shifting)

warrantied for 5 years/60K miles

 

"warrantied for 5 years/60K miles"

What? 4 year/50K miles & is likely past warranty anyway.

 

here in canada warranty is :

basic : 3 years / 60 000km (4 years / 80 000km on 2006+ models)
powertrain + a lot of other stuff : 5 years / 100 000km
auto tranny : 7 years / 160 000km

1 mile = 1.609 km

 

 

my dealer told me the manual tranny was only on the 4 year/50k warranty.

was this correct?

 

Yes... The 03 CL 6spd only has a 4 year/50K warranty...

<--- 4 years/ 53K miles now

 

so this is definitely an unfixable problem w/out getting a new tranny? it does the same thing on my 98 5mt, but only when i redline it. i know its not my fault because i have tried redlining, clutching, waiting a second, then shifting and it still does it. the car has never had a new clutch. could that be it?

 

you don't need a new tranny, only replace faulty gears with syncros and you'll be fine.
