I need manual transmission for my grand am gt1 3.4 2004 that i can put in my car.If is possible.

they never made a manual for the 3.4. they did make a manual for 94&95 3.1's but i couldnt tell you if it would be compatible or not

Do a search for this on www.grandamgt.com - It seems like i remember someone on that forum doin it - if I remember correctly the 3.1 tranny will work with 3.4, it's just a real PITA to change an automatic to a stick. You'd almost be better off just to buy a different car - but search on there and you should find some decent info
