Transmission Problem

[tannie]

hi there , my name is tannie tam from malaysia

i got 2 main issues occurred on my car.

1. 5th gear cant engage

2. lsd making very loud noise

acutally i am driving a cefiro a31 , then i transplant the r33 rb25det into my car. then everything is fitted into the car nicely. then when i am about to test the car, then i found that i cant engage to 5th gear. i try to engage to 5th gear and i crank the engine(the car is on the 2 post lift) , then the gear lever just pop back. i tried with 3rd and 4th gear , it doesnt pop back . i did check for the clutch pump and all the other stuff , but everything is ok. i really blur now ?? dun know wat to do ?? i planned to drop down the gearbox and check it out wat is happening inside the gears , i hope the 5th gear is ok. coz i really tight of budget now ?? if u guys have any comments , pls help me

the 2nd problem is the 2 way lsd that is previously install to my car since i am using the previous engine (rb20det) , now is making noise. last time the lsd s working fine. or is this normal that the lsd will make noise coz i didnt drive the car during the transplant ?? the car is in the workshop for about 1 month ++ . yesterday i do a test drive ( slowly ) and the lsd is not working like before. then today i did drive the car around , making few turns hope to run in the lsd ?? is there any comments from u guys about this problem.

hope to get feedback from all the members

thankz a lot
