1g 1.8 & 2.0 N/t tranny ?'s

My transmission in my 1g eclipse GS is grinding in 4th gear and most of the time it pops out of 4th, and also i am slowing lose'ing my reverse gear.

After searching around i found out that 1g 1.8Liter and 2.0Liter eclipses came with both (f5m22) Manual trannys. So to make my question short are the 1.8 liter trannys a direct bolt up to a n/t 2.0 4g63?

I think you answered your own question right there...

i just wanted to make sure, due to i had prob's with other cars with certain parts being the same part number but then the parts being different in mounting design.

thanks man
