my friend has a b16 swapped eg. he is selling his tranny to get a gsr tranny. i want to know a few things before i buy it. one night he went to run a k20 integra from a 40 and when he went to go to 3rd in went into 1st. now he can put it in 1 while do like 40+mph. also it grinds third gear a little bit. and i was wondering if i put the lucas tranny stuff in it will it clear that 3rd gear grind up. but my man concern is that 1st gear blocker thing. thanks in advance.

 

I don't think any type of transmission fluid/treatment is going to fix a grind or not going into gear problem. It my experience it may fix a notchy or rough shift but it usually comes back after a 1000 miles. Its going to need a rebuild for sure.

 

does it grind only when ypu shift it fast? or is it all the time?

 

just shift it fast. but what bout that first gear blocker gone

 

bump

 

rebuild it..

 

i have tha same problem in 3rd gear and my bubby is a tranny expert and he's to rebuild it

 

well ask him how much it would be at a local shop.

 

also, ive heard castrol gtx syncromesh works pretty well with the 3rd gear grind, i have yet to try it

 

penzoil syncromesh does work... as long as its not a terribly bad grind. i used it in my b16 trans before last summer. and now i only get the occasional 3rd gear grind.

but ya 40mph downshifts into 1st are no good. :/

 

do u know what could fix that beside a full rebuild?
