Does a stock 4 speed Tranny bolt on to a 3.8L? (Page 1/2) |

I'm sure this has been asked and answered but if I want to do the 3800sc swap will this motor fit the stock tranny (85 GT 4 speed transmission in an 85 SE)? if not where can I find adapter kits? thanks

Yes, IIRC all transmissions that came in the Fiero have the same bolt pattern as the 3800. The muncie (which is your transmission) also happens to have the strongest casing that was put in the fiero. Of course, you won't be able to abuse the trans too much because the power will break it. For in town driving, the 4 speed is probably the best way to go because of the gearing. If you drive on the high way a lot, you might want to consider upgrading to a 5 speed F23 trans.
BTW, welcome to the forums! [This message has been edited by zzzhuh (edited 06-10-2015).]

Yes. All 3800s use the FWD bellhousing

I'm sure its no worse on the highway than my current stock automatic set up.. that thing costs a fortune on gas. Do you have a recommended build thread to follow by chance?

i am using the 4 speed muncie tranny, and the middle right bolt (as you face the engine) refuses to go in. The engine is a 3800SC off a 2002 Pontiac. The threads aren't stripped, in fact i can see no threads, but could there be a sheared off bolt in there? i do need all 6 bolts no?
