96 honda civic transmission replacement/repair

[bigazowl]

guys, need advise sana. My honda civic 96 LXI has already problem with its transmission medyon nag-slide na kc. Ask ko lang magkano ba magagastos ko dito if ever sa casa ko ipagawa or kung bibili na lang ako ng surplus then pagawa ko na lang sa kilala kong mechanic.

Thanks in advance for the replies.
