Hello all!

 

So over the winter I have noticed a slight crunch or notchyness (it is a word) going to 1st to second regardless of the rpm. It goes away a bit after an hour of driving once the old is warm presumably.

 

Question is what could it be? - It is rare for the 2nd gear synchro to go. If I change down from 3rd to nd it is smooth. So if all in one movement I go from 1st, move into 3rd with clutch depressed, then put it into 2nd it is smooth as silk.

 

I will put some MT90 in and see if that helps. Some guy on zcar mentioned that it could be clutch boost? does this mean anything to anyone? http://www.zcar.com/forum/12-90-96-tech-discussion-forum/161527-300zx-gearbox-probs.html

 

Best, William.

Its funny you should say that not funny ha ha . mine has trouble going into first and somtime i feel like its not going to so i have to put it into secound then first just to get it in but im assuming its something that ive overtightened when i took the engine and box out plus i dont know if the gearbox oil was toped up, dont know if that makes a difference. and also proberly not related sometimes when when om the gas in motion in norm conditions i can feel the clutch peddle move when driving. is that good or bad. may be all related mate but itll be intrested to know. hope you sort it.

Most likely the 20 year old gearbox oil mate the mt90 will likely make all the difference. You will want a sump plug key to make life easier. If you want to borrow a set I have a set but they're cheap enough from halfraids. Top tip, undo the side one first! If it's seized you've still got oil, if you drain it first you get the idea...
