Hey everyone, so my 04 srt 4 since I've had it, has driven okay, here and their when its hot it will shift a lil hard into gears but I've I try to downshift into 3rdit goes in but as soon as I let the clutch out, cruuuuuuunch but I can up shift into 3rd fine when I go threw the gears. I changed the fluid with atf4 and a Lucas oil stabilizer but still the same. The guy I got it from says its the clutch but its the synchro isn't it? How hard would it be to take out the gears and is it cheaper to buy synchros on my own? Input and advice guys?

My car used to pop out almost every time I downshifted into third. The extender is just a bandaid fix. Once I installed a new clutch (act xtss) it hasn't done it once. I rarely even downshift anymore because how violent the vibrations are because of the stock tranny mount :rofl: that will be next on my list.

The gear extender IMO is a band aid fix you should replace the synchro. Are you having trouble getting it in to any other gears?

Not really, I notice sometimes after driving for awhile, it will tough to get in to first and second will take a bit to get into but still goes in.......the fluid change I did seems to help so far but I mite drain it again and fill it with the Mobil 1 high mileage oil but I'm wondering how much synchros cost......

The hard to get in first is probably the clutch fork and pivot ball. The synchro is going to cost around 350.
