Looks like a granny four speed to me

**special-K** · 10-11-2005, 06:54 AM

The automatics have their own cross-member,you`ll need that.

**truckdude239** · 10-11-2005, 08:45 AM

looks like an 4 speed granny transmission to me there good trannys had one in an work truck and it would pull anything around work

Where are you in Mexico? Maybe I can help. I've done the swap and can give advice or if you are close lend a hand.

You will need:

1. Cross-member from auto truck
2. Remove manual cross member
3. Vacuum line to modulator from carb
4. Kick-down cable set up

My swap went well. I installed a Hurst floor shifter rather than trying to replicate the shifter on the column.

GOOD LUCK !

I have a similar tranny in my garage right now, it's a 4spd. Been trying to get rid of it forever.

Still have the tranny? I am thinking of taking my 3sp out for a 4sp. Need to research and see if it will bolt to my '69 transfer case. Any help on this?

Still got it. Trying to rid of it. I have never run it, but it looks to be in good shape and the board member I bought it from said it was working great. PM me your thoughts - don't want to hijack the thread.

shifty · 10-11-2005, 04:42 PM

The 4spd in my garage looks like a SM465 or the NP435.

llegos · 10-11-2005, 07:12 PM

Im gonna say its the SM465, cuz my NP435 doesnt look like that on the left side

Longhorn Man · 10-11-2005, 08:06 PM

Don't forget a tranny cooler too in addition to the list above.

sdmahr · 10-11-2005, 09:46 PM

Good call LongHorn ! I forgot about that new radiator with the cooler built in I had to buy! A good add-on would also work if the radiator he has now doesn't need replaced.

**truckdude239** · 10-11-2005, 10:03 PM

hey shifty your 4 speed is it granny if i not how much u want for it?

**kwmech** · 10-11-2005, 11:27 PM

That is a 435----just like the one in my 68 GMC. The 4 bolts on the back holding the output housing is the give away.

I know very little about this transmission. Only asking $100 for it, which is what I bought it for not even 4 months ago. Hell, I would give it to you for $75 since you'd hafta come pick it up.

I bought it from another board member down in Orlando for between $100-$150 (I forget). I have most of the brackets and crap that came with it. Need to get it off my hands. I can shoot you some pics if you want.

Ok, so I know more now. It's an SM465 for sure and it has a torque converter attached. According to a website I found about the tranny, here is the info:

The Muncie 465 is the widest ratio 4-speed of the Big Three. It has a granny low and so then just 3 normally usable ratios.

Here are the gear ratios from drivetrain.com:

1st :: 6.55

2nd :: 3.58

3rd :: 1.7

4th :: 1

Thanks

Not trying to hijack, but that's gotta be a new steering wheel? Looks great!

ChevyMex · 10-20-2005, 03:21 AM

Mr. KWMECH, do you know if this tranny (435) has somewhere a place to put the back up switch?

Blazerb61 · 10-20-2005, 07:16 AM

the back up switch is located on the top left corner maybe broken off

ChevyMex · 10-21-2005, 01:25 AM

The steering wheel is not new, i have restored it, polished and painted the cap, even the model is a 1969 in Mexico the steering wheel came with this kind of cap 69 thru 72 models. Another diference is the bed, complete diferent the rear wheel arch is square not like in circle. I have some photos but do not know why i can not post it anymore..

I have looked the top left corner and nothing, any photos?
