3.4 Trans same as 3.8?

[pgriffith]

Quick question. Is the 3.4 and 3.8 manual transmissions the same? Are they interchangeable?

[viper98885]

The transmissions themself are interchangable but the bellhousings are not.

[pgriffith]

I cant remember are the bellhousings removable on these tranny's?

[Fedaykin]

of course

[FlamespikeMST1]

yes the bellhousings can be taken out. the reason bieng why the you would need a different bellhousing is because of the bolt pattern
as the 3.4 is a 60 degree where as the 3.8 is a 90 degree engine respectively

The input shaft on the 3.4 T5s are different than the 3.8s, so you'll have to replace that as well.

is this a big job? or a simple matter of changing the parts?
