Title: Trans. change - need your advice Post by: grandam455 on September 18, 2013, 10:00:41 pm I was told that the sunfire auto trans. will bolt in to a fiero with 2.5 with no problems just add a shift improver, I have a 1999 sunfire that is rotted out but trans. works good and would like the overdrive, has anybody done this? if so any problems or is it a bolt in. Your advice on this trans. change would be greatly appreciated. Thanks Tom

You will need to make mounts and a shifter bracket to get it working and deal with the tranny VSS that is most likely not the 4000 PPM that the Fiero uses. Dan

Make sure the motor looks like this: Title: Re: Trans. change - need your advice Post by: aaron88 on September 21, 2013, 07:28:20 pm Like Dan said, you will also need one of these to convert your speedo signal.

Yes aaron that is the engine. I appreciate your advice as I am just looking to improve the drivability of the 2.5. Tom
