Originally it had a 3 on the tree, 4 side bolt side Muncie. Due to unavailabilty (and severe lack of funds at the time) I swapped it for a Muncie 4 spd. Now, I have to swap it to an automatic (bum knee). I've read the articles listed, but the seem to be geared (sorry, had to) for trucks older than mine. Q: What automatics will fit and work well? Thanks, Pal

I would not use O.D. around town or going over long hills especially when towing. Other than that. You will need to use a driveline for the same truck you have W/automatic. Should be fairly easy to find. The TH-400 will have a different output shaft so you will need the slip-yoke for the TH-400 and there are u-joints that will fit the yoke to the driveline if needed.
There is enough good in the worst of us and enough bad in the best of us that it does not behoove any of us to criticize the rest of us. - - Be yourself. If you are ever lost, It will be much easier to find yourself if you know who you are!

If you have 3.90 or 4.10 or 4.11 gears go ahead and put in a 700R4 - expecially if you do any long distance driving without a load.
Sorry to hear about your knee - I would be bummin if I couldn't use a clutch. | | |

It's not as strong as the 700R4, but more than adequate for the 250. I would advise against the TH400, it robs several horses. The TH350 would be a better choice for a 3 speed behind your engine.
Some people swear by the Powerglide, which was available in 68. I had experience with the back then, the only one I had success with was in a Nova behind a 194. It is another option.

It is said the ratios in the lower gears is closer compared to the 700r4. Not all mods would be needed for lower power daily drivers. Supposed to be an easy install(conversion) Good luck and let us know how things go.Tom

And Ken, the knee isn't terrible, just gives me trouble if I get stuck in traffic jams (in Seattle area? Naw, we don't get those) Mama just gets tired of me limping...... Anyway, it'll probable be awhile till I make the conversion. I just blew all my spare cash on 250 LB from Ram in Spokane. I get to install it in a week. Thanks again all.
