F40 transmission (Page 1/1) Fieromotion NOV 13, 02:10 PM Want to buy F40 transmission in good working order. I think it was in Pontiac G6 GTP maybe others. Need to have the same attaching pattern as other GM engines as 2,8, 3,4 engines. It will meet the 3.4 TDC engine in my 87 Fiero I think what I need.
