99RegalGS Posted February 20, 2004 Report Share Posted February 20, 2004 I'm assuming you want the Series II 3800. I'm almost positive that the NA 3800 and the 3100 tranny's are the same. You might need to get the subframe and engine mounts from a 1st gen 3800. you need all the wireing also. as for hardness, I think it would be harder than a regular engine swap since you need to change a few more things.

No, the transmission model number and bolt up are different. You can modify the bell-housing on the 4T60, but it's not going to hold like the 4T65-HD. When swaping powertrains, make sure to grap everything: engine, tranny, ECM, etc. - Erik Quote Link to comment Share on other sites More sharing options...

4spdz34 Posted February 21, 2004 Report Share Posted February 21, 2004 there is no difference between the 4t65e housing and the 4t60e housing on 3.8 and 660 motors. none notta nothing. Quote Link to comment Share on other sites More sharing options...
