6-Speed Fiero Transmission Conversion Kit

Our New 6-Speed Fiero Transmission Conversion Kit allows you to mount the new Pontiac G6 6 speed transmission into any stick shift Pontiac Fiero.

In 2006 Pontiac introduced a new to the U.S. 6 Speed Manual transmission in the front wheel drive G6. This new transmission is a FWD transaxle much like the manual transmissions in the Fiero. As you may know, we’ve been selling & installing V-8 Conversion Kits for the Fiero for nearly 20 years now. It’s only a “natural” for us to want to try to fit that new 6 speed into a Fiero.

We’ve now designed a kit to enable this new 6 speed to be installed into all stick shift Fieros. If you have a stock Fiero engine or a SBC engine swap or anything in between, we have a kit that will allow you to install the 6 speed. As you might know we do a lot of Chevy V-8 conversions here & have a lot of customers out there with SBC’s in their cars. The SBC version of our 6 speed conversion allows the SBC guys to use all of the major parts of their original V-8 conversion when retro-fitting the 6 speed.

The G6 6 speed is just ¼” longer that the Fiero Getrag transmission. The end of the trans that is the closest to the left side frame rail is larger in profile because that transmission has 3 gear shafts instead of the Fiero’s 2 shafts.

The G6 just started using the 6 speed in 2006, so you don’t see a lot of them in the salvage yards yet. They are available now at your local GM dealer parts department. As you will see, a large part of the total cost of the swap is the G6 specific parts. The swap can be very affordable if you can obtain these parts at a salvage yard.

In addition to the transmission this swap requires several other G6 driveline parts. We have 2 versions of the 6 speed conversion kit. The Economy 6 Speed Conversion Kit includes all of the custom parts that it takes to complete the conversion & allows you to buy the needed G6 parts on your own. The Master 6 Speed Conversion Kit includes all parts in the Economy kit plus all of the new G6 parts that are needed.

The Economy 6 Speed Conversion Kit includes these parts: At one point or another, you will need all of the following parts to complete the swap.

The price for these LSx specific parts is $235.00.

Note B. If you are obtaining this part on your own, it will be necessary for you to send it to us so we can do a LSx specific modification & ship it back to you. Cost for this modification is $110.00. This modification is only needed on LSx engines.

Note C. If you are obtaining this part on your own, it will be necessary for you to send it to us so we can Pre-assemble it for you & ship it back to you.

Note: You will need to use a modified 4 speed Fiero shifter to complete this swap. If you send your shifter to us, we will make the modifications & send it back to you for $ 150.00.

Note: You will need to use 2 Fiero Getrag Select Cables on this swap. (we recommend using new cables from Rodney Dickman) 1 of them remains unmodified. The other Select Cable needs to be modified. You can send that cable to us & we’ll do the modification for $80.00 or we can provide a new modified cable for $240.00.

Note: If you are also getting a quote for a V-8 engine swap kit, some of these parts are redundant with parts supplied in that kit, so the prices will be reduced accordingly.

I hope this information has been helpful.
