    I'm taking automotive tech. in college and I'm going to swap out my stock 700R4 auto for a 5 speed manual. My manuual drive train instructor thinks I may have to modify the tranny tunnel to clear the bell housing of a manual. Am I going to have this much trouble with this? Hope not.
    Any info. is much appreicated....


    Thanks,

    I don't see why the bellhousing on a 5 speed would be any bulkier than one for a 4 speed. GM had lotsa 4 speeds in these trucks over the years without any tranny tunnel issues and they all fit quite nicely.
    What kind of 5 speed are you swapping to? (NV 4500?[​IMG][​IMG])

    Haven't they taught you how to use a small sledge hammer yet? [​IMG] It's the perfect tranny clearancing tool! [​IMG]

    I'm not sure yet. The guy I bought my K5 from is buying anounther for $100 for me that has no interior and no motor. all thats left in it is the front rear axles, drive lines, transfer case and 5 speed so i'm unsure of what it is. All I know is if he is going to give it to me I really cant lose, It also has most of the body{fenders,tailgate,hood, doesn't have the top on it though, its a 73 with the full removeable top, It also has the front and rear glass} I will probably just sell what I don't use such as the frame and maybe axles, and body panels. Thanks for your time and efforts.

    Thanks,

    They didn't have to teach me that is what dads and grandpas are for, they taught me that a 3lb or bigger sledge is a universal tool.

    I think you might have a problem with a stick. Does the tranny hump unbolt from your truck? I would guess that it doesn't. You just might have troubles swapping in that 5-speed. Those trucks never came with a 5-speed, so it's prolly a late-model Getrag (junk) or NV4500 (golden), both of which have shifters that are an inch or 2 rearward of where an SM465 would be normally.

    Just get the swazall and a good narrow blade and go to work.

    See Hawglet, you already have all the training required to install that tranny. ;-) With a BFH and a Sawzall you can make almost anything fit! [​IMG]
