When I drove my car one night it didnt want to go into 3rd and 4th too easy and grinded 4th Its a hydro LS btw. So I was like ok the synchros are going but on my way back home it shifted fine??? Now when im at wot its hard to get it into second and grinded once but if I take it up slowly It goes in easy and it grinded 3rd once at WOT then during regular driving it grindes 4th every once in a while.
It does not grind every time so i dont think its the synchros cuz it grinds any gear at random maybe its the clutch?

It is probably the synchro and sleeve going south. certain combination of teeth sleeve combinations may net you a grind or no grind. When was the last time you checked your fluid?

m-

 

Replace your clutch before its too late.

 

I changed my tranny fluid with honda MTF the next day(there were no metal shavings in it), I dont think sychromesh will help me now

And it only grinds while shifting, randomly

So... clutch or new tranny?

nobody knows?

 

anybody

 

im wondering this myself so i think here is a good place to ask... will the GM synchromesh fluid help any? i know the 88-91 lsd tranny guys love it.

 

idk IM trading the car on sunday I just want to know so I can tell the guy whats wrong with it, I'm leaning more towards the clutch/pressure plate correct me if im wrong but the 2nd gear synchro has nothing to do with the 3rd gear synchro and theres no way one synchro will make 2nd 3rd and 4th grind once again it doesnt keep grinding the same gear it takes turns with 2nd 3rd and 4th

 

what kind of car is it in.....if its cable when my b16 clutch was goin it grinded changed it and it was fine....if it is hydro as in in a hydro car its the slave cylinder, pull the boot back and if it leaks fluid its shot

 

Yea its a hydro and I plenty of fluid, it does have a small leak from the clutch cylinder(the one that bolts to the firewall) but I check my fluids often, I'm almost sure its my clutch so if this trade doesnt go through on sunday its getting replaced and I'll let you guys know the results for future references

 

pull the boot back on the SLAVE cylinder if it leeks fluid thats your problem

 

yup its the clutch when im rolling around 1-2mph and put the car in 1st it shakes slightly
