79 Grand Am 5 speed
I had the transmission sitting in storage for some 17 years and the 4 speed with 3.42 gears had poor high speed cruising. This Christmas was grand am time and the conversion was completed.

So, was this car an original 4-speed Grand Am?
That appears to be an A/T console. The 5-speed must have nice tight shift throws. |

it was an auto car converted to 4 speed, otherwise I would have left it stock. The 5 speed fits well with the exception of the cross member and drive shaft( they needed some modification). The extra length of the transmission positions the shifter in the correct location of the auto console, it shifts like a knife through butter

That is cool! What 5spd did you use? Did you keep the mechanical linkage clutch? I'd love to swap mine to a 5spd but would have to have a hydraulic linkage. With my back, I can't drive a mechanical linkage anymore, too painful.

I used a borg warner T5 from an 88 trans am, and the clutch linkage is mechanical but its not heavy at all. the 4 speed t-10 shifted like an old truck, this 5 speed is light to shift |

Very happy to see this car find its 2nd life. This was a very clean well done car to begin with.

It was converted to a big block and four speed by the previous owner otherwise I would have kept it original, The five speed cleaned up the installation, improved highway cruising and made it possible to re install the automatic console. |

I was going to change it over to a 455 but this 350 runs so well that it would be a shame to change it.
A testament to the previous owner and his machine shop, I just changed the carb over to a mid seventies trans am quad with electric choke and tall chimney for the early gto/ firebird air cleaner assembly. |
