    NP205\'s and OD Manual trans.

    First off, I'm getting psyched, we are starting to have our meetings for the upcoming truck pull season (stock class safety rules/equipment discussion tonight, since we had a few "mishaps" last year with clutches grenading).....sorry had to add.....but anyways, one of the guys in our club wants to have a manual overdrive tranny and the NP205 t-case. A.) I am an auto man and the only manual I have had any experience with is the sm465. B.) He is not the most mechanically inclined individual, but he does currently have a 83 K30 with swapped in sm465 and NP205 (was an auto with 400).

    He was looking for what Heavy Duty overdrive manual trannies are available to mate to a 205 and what will he need (adapters) to mate it to his current 205 (if it's possible). I don't know jack about this, so I told him I would ask for your input.

    TIA

    Chris

    He could use a NV4500 adapted to a NP205, for something like that have him try Advance Adapters.

    A Clark or Eaton 5spd (Medium Duty Trannys)could be made to work with the 205 also, but I’m not aware of many “kits” for them.

    It would take allot of driving around in 5th gear to offset the cost of such swap if fuel economy is a concern.

    I can post the URL here tomorrow for an NV4500/205 conversion that was done (I believe) by a fellow CK5'er, including part number breakdown and pictures. If you want

    Sweet! Thanks, I'll pass it on. I don't know what will be different (as his was a sm465 and the tranny listed in the article is a 700r4), but it should give him a good Idea.
