1st to 2nd grind.... - 2003-04 Mach 1 Registry Owners Club

BallisticG · 07-10-2008, 12:08 AM

i am getting quite a bit of 1st to 2nd gear grind, i am going to change out the tranny fluid this weekend, but my clutch is engaging and disengaging like half an inch off the floor, do the stock 2004 mach 1's come with the firewall adjuster and if so how do i adjust it? any help is much appreciated, thank you.

no firewall adjuster.

i think the proper procedure was with the car off and in 1st.
lift up on the clutch pedal then slowely depress and you should hear a click and that would be the factory quadrant adjusting.

Im getting a 1st to 2nd grind unless i shift slowly and mine is suppose to be the syncros going bad.

Synthetic oils helped a lot for me.
1-2 grind GONE, 2 -3 much less prone to missing (it still does when cold from time to time, but granny shifting for 5 minutes is really not an issue.)

I've heard that the gearbox is very sensitive to oil level - might be worth a search.

probably the 1-2 blocker ring on the synchro try 2 quarts of mobil1 atf and a 1 quart of lcas tranny lube and se if that helps. thats the mix i use in my tranny and its still a stock 3650
