5-speed swap HELP???
I have a 1972 GMC Longbed that has a 350 with the stock auto transmission and I am wanting to put a 5-speed manual in it. I am planning on going with a TKO 500 but I heard that the TKO 500 is a little bit taller than the T-5. The reason I'm wondering is my truck has the low hump tunnel and I want to make sure that it will work with the lower tunnel before I jump into the deepend so to speak. Any help will be much appreciated y'all.
Thanks: Billet man!  Posted via Mobile Device |

Re: 5-speed swap HELP???
I'm putting a Tremec in my '67 - I will post pictures when it's done. It's in the truck right now but from what I can see, it's not very tall - I'm gonna have a custom tunnel made, but it looks like a high hump will work just fine. When you order the tranny, just get it built for the middle position so the shifter is not too far back.

Re: 5-speed swap HELP???
i believe that you will need to use a high hump for the TKO.
I have had a TKO in my 71 shortbed stepside for many years now. Here is a link where I discussed this years ago with a picture of the TKO installed with the low hump floorboard in place. http://67-72chevytrucks.com/vboard/s...d.php?t=223031 |

Re: 5-speed swap HELP???
I really appreciate all the help ya'll!!! I was looking for more information on the Keisler SS700 but I couldn't find much about it. One of the main reasons I was looking at the TKO 500 is www.hurstdrivelines.com makes a transmission kit for the 1960-72 GM Trucks and it comes with everything for the swap, plus a manual is SOOOO much more fun than an auto!!!!!!
 I just talked to the tech there and he said that they put one of those transmissions in they're '66 CHevy with the low tunnel and it fit just fine but I dont know if the tunnel is the same size on my '72 as it is on they're '66. Any idears????www.billetworkstactical.com |

Re: 5-speed swap HELP???
I have a tko600 in my 70 with a low hump....fits like a glove but was a little close in the pinch weld area where firewall meets floor pan, but I dont think I even did any bending . I used an auto crossmember and left shifter in the rear factory mounting hole but mounted it backward to move it forward a couple inches to clear my bench seat. Drive it daily and LOVE it!!! Glad to answer any question or try to send you pics.
