Hi Everyone,

I've got a TH440 transmission that I'm going to put into my 88 Formula to replace the TH125. I've done some reading and am wanting some input from you guys to be sure that I'm getting the other parts needed to install the transmission.

CV axles:
I found on http://snowcloude.com/~banner/FIERO-4T60.html that ones out of an 87 Pontiac 6000 part number 5257 and 5258 are supposed to work. I find on http://www.pontiacperforman...es/4_speed_swap.html that Cardone part numbers 60-1078 and 60-1115 will work. Can anyone let me know if these part numbers are correct or if you have some others?

Transmission mounts:
I found http://www.fierofocus.com/T...%20Transmissions.pdf , It tells me that a 1992 Pontiac Bonneville (3800
vin L) work in Fiero applications, and the OE/stock Fiero rear transmission mount will work on the back of this transmission as long as you have the formed/stamped steel bracket from a donor Bonneville or like-bodied car that bolts to the left-rear of the transmission.

Am I missing anything else that I need? Any help is greatly appreciated.

Thanks,
Mike

I found the GM part number for the transmission mount bracket mentioned in http://www.pontiacperforman...es/4_speed_swap.html. The GM part number is 22145828, which has the bracket as part of the mount.

I had to order a governor assembly for my 4T60 transmission since it was the one that wouldn't work with the Fiero. I ordered the parts from http://www.txchange.com. I paid $40 for the parts and $14.72 for UPS shipping to South Carolina. Their part number for the governor assembly is RK84410
