My transmission is making a grinding noise when I shift into reverse. Is my tranny about to die? The only thing that has been done to it was a corvette servo install about 3 weeks ago. The transmission fluid appears to be at the right level. Any ideas??

also, how do you check the tranny fluid without taking anything off? other then mabey the fill spot on it.

Clutch is going out?
With the hydraulic systems the clutches are good to the last drop.

meaning.....


they dont wear out as quick?? cause i have a hydralic one...

Redliner

No... wear patterns are linear. It's good to the last drop, meaning that the clutch is good until it is really ready to crap out on you

how do you check tranny fluid with out physically taking the tranny out.. obviously there is a way.. im just an idiot

jfreeman74

I'm not sure about your car but mine, and all other cars that I have seen have a dipstick, just like the oil. It is close to the firewall.

84Z28_5.7ltr_V8

i definatly dont have one of those

Redliner

T-5: two holes
one drain one fill
Put car on stands
Use standard socket wrench
Insert into the top bolt and romove
insert pinkey
Feel for fluid
fill till it runs out.

Best way to fill. You will under stand if doing it alone.
1 squeeze bottle
4" of rubber hose. collant over flow hose 1/4" id
Fill with ATF
Don't post to verify ATF, USE ATF

Some body doesn't know their cars here?

One of you has a t-5 and the other has a 700r4

someone needs to clarify themselves

jfreeman74

Apparently 84z28 has a T-5. I have a 700R4.

84Z28_5.7ltr_V8

lol.. which is better?? T-5 or 700r4, whats the difference? im still kinda new to the whole car scene, i know lots of ****, just not everything.

Redliner

t-5 Manual (T: top loader, gears go in from the top of the case , 5: 5 speeds)
700R4 4 speed auto with last gear being over drive

84Z28_5.7ltr_V8

ohhhhhhh!! thats what i figured but i didnt know that toploader ****.

hellfire

just a little advise, if you are grinding into reverse. first put the trans into 5th, that will synch the gears and then put it into reverse. this will keep you from grinding and extend the life of your trans. not a fix but a little help.

84Z28_5.7ltr_V8

so grinding is somewhat normal??

84Z28_5.7ltr_V8

by the way, mine doesnt really grind, it sort of goes.. grrrr THUNK!

lol

jfreeman74

That is what mine is doing. But only when going into reverse.

hellfire

Yep, it did that on mine when i first got it. Reverse is not a synchronized gear so with wear it will grind. i always put it in 5th and then right into reverse and no grinding.

84Z28_5.7ltr_V8

im giong to start doing that, thanks for the tip!

hellfire

You bet, thats what were here for.

i have a 700r4 trans and it grinds in reverse and when its in drive anybody have any thoughts on it?

Dizturbed One

Do the above. If it is still tough from time to time, pump the clutch once while in neutral, THEN put it in 5th and reverse.

Grinding in reverse is usually a clutch adjustment problem however. Make sure you have the proper free play adjusted on it, that it is fully bled, and the slave cylinder is completely full

If adjusted properly, it should stop the grind going into reverse
