My damn third gear keeps grinding for some reason. Could it be transmission mounts? Shifting feels a little off.

 

shift linkage would be first thing to check...

3rd syncro ring may be worn out too

wouln't hurt to inspect the mounts as well

 

Now that you say shift linkage, about a month ago, i ran over a semi tire retread and it snatched it out of third. I dont know if that is the cause of it or not, but you did remind me of that.

ahh, yes. with this in mind: linkage is first place to look. i'll bet it's damaged

 

when was the last transmission oil change? Look into Syncromesh (penzoil) it works for some tranny's that grind, unless your really really grinds but hey try it anyway!

i always add a little Hypoid when i change the tranny oil, but i don't understand how an additive will stop 'grinding'...

Give GM Synchromesh Friction Modified a try. It does indeed smooth out shifts considerably. While it won't necessarily stop a grind, it can reduce grinding.

 

Thanks everybody for your advice. Now I have at least a place to start solving this problem.

 

Synchromesh got rid of my third gear grind in my tranny.

 

you might wanna stop using the hypoid oil..........



Also, people who blame D series synchros have no clue what they are talking about

 

Check your clutch cable freeplay. I have to constantly adjust mine (I think my PP is wearing out) to stop grinds...

 

I just bought 3 quarts of the syncromesh today, they said they didn't have the friction modified one though. Should I get some quarts friction modified and take these back or should it be fine?

 

why the **** would u put some hypoid oil in your tranny.

no wonder its ******* grinding.


DONT USE GOD DAM GEAR OIL... sigh

 

tranny shop replaced the ISB, tranny made noise so they added more fluid.......
