Tranny notchiness/grinds

[AccordEpicenter]

My tranny in my lxi has been a little notchy and somtimes grinds when shifting its got 10w30 in it i think im gonna try GM syncromesh Friction Modified in it and hope it works, ive heard its good for honda trannies, have any of you tried it?

[Justin86]

hum yea I have a problem with my 3rd gear sync and my 2nd gear sync is trashed. So is this just an oil that suppose to make everything smoother, casue I really don't feel like going through my tranny again.

[shepherd79]

i wouldn't use that GM crap.
if your synco is gone, nothing will bring it back. on my old tranny the synco on 1st gear gone and i tried everything and nothing helped.
your only choice is to replace the hole tranny with better one.

Why use GM synchromesh when you can use honda MTF, its basically same same formula. It wont fix anything but it may make things a bit more livable

[Justin86]

this syn in 2nd is gay, when I try to shift hard into it like at 6K about 80% of the it grinds, kind hard to win a race like that. I have extra trannys for parts and more gear ratios but I don't want to take the time.

the only thing that grinds in my tranny is the damn reverse
Kinda gay when you parked with your buddies and everyone goes to back out and they hear GRrrckkklack.....and see me back out...

Like is always say: "Can't find it, Grind it"

Here is a way to not grind the reverse gear. Put the shifter into a forward gear first like 1st or 2nd and then shift to reverse. The reverse gear has no syncronizer so you have to stop all the gears in the tranny before the reverse can slip in quietly. Try it, its guaranteed to work.

[AccordEpicenter]

yes and first is semi syncronized. Right now i have 10w30 in it, if i went with honda mtf it should remove tons of the grinds and notchiness. The gm syncromesh is almost the same but the friction modified seems to be better

when my second and third syncros were messed I used honda MTF and one bottle lucas tranny fix did wonders til I had cash for a rebuild

[FishyMan]

i've experience grinding in only the Reverse gear. i dunno why. all other gears are fine.

im trying to park and adjust, i got into 1st and want to reverse, and when i do all the 1st then r, or n, 1, r, and stuff it still grinds.. i've found that pausing and putting it in neutral and then first, then neutral then R it will smooth out... i dunno why, what's the logic? sorry noob here..

[AccordEpicenter]

fishy... the reverse gear is not syncronized, so it will pretty much always grind (even with a BRAND NEW TRANNY... nothing is wrong with it) you must go into 1st before reverse because 1st is semi syncronized, so it wont grind into reverse when you shift provided you arent moving when you do it.

[Justin86]

It also helps with the RPM being down low before you go into reverse, that when I get most grinding problems with it when it is at a high idle 1500+

[AccordEpicenter]

very true

Ok i swapped to GM synchromesh FM yesterday and already the tranny shifts better and grinds much less than it used to, and the notchiness is gone... im told that after a few hundred miles of driving it should have more of an effect...

[johndej]

hmm....... i've always heard that honda MTF and a 1/2 bottle (whole in some cases) of Lucas tranny fix will always make things better.

[AccordEpicenter]

yeah ive heard that some lucas and mtf or syncromesh is good... full synthetics in the gearbox is bad however

UPDATE>>>>>

GM SYNCROMESH FM IS GOD!!!!... After a week of driving, my syncro grinds are just about gone. Now to combat missed shifts which put me in this situation (3rd gear throw is LONG in accords and thats why i missed a few 3rd gear shifts and started grinding, now as long as i dont grind any more i should be ok) so now i have a pacesetter short shifter coming for the car... it also has a little side to side wobble in the shifter, no good for acurate shifting.
