I just bought this 83 K10 and it has a 4 speed

[GOPAPA]

Muncie transmission .. I got what I think is a good deal and decided to buy this one and go back to my shifting days ..

I do have a question though,, are these Muncie sm 465 4 speed transmissions going to give me a hard time shifting a lot in the city where it's stop and go between lights?

It has been a long time since I have had a manual transmission ,,but I read that these have a wait time between shifting gears up and down

Any thoughts on this ?

I have never noticed a big wait time.
They are not like the 4 speeds found in cars though.
It's not a (Speed) shift transmission

1st gear is not a syncro'd gear. 2nd, 3rd and 4th are synchronized.

Just drive it and see what you think.

The worst thing about stop and go traffic is the constant clutch pedal usage. A slow 2nd/3rd shift is not as big of a deal. Other transmissions will shift faster, but you'll still have to use the clutch.

Converting to a 85-87 hydraulic clutch would make the pedal effort easier, and supposedly converting to an internal slave/release bearing would make it easier yet.

Daily driver ? If so and your in heavy traffic a lot….it will get old fast.

I have a couple of trucks with the SM465 and they seem to be damn near bulletproof proof. One of them (84 K30) has a 460HP big block in it and I drive the hell out of it, I shift it as fast as I can, which is not very fast

Nice truck

Most sm465s that I've owned I didnt even need 1st gear...always started in 2nd unless I had a load or on a hill...I've drove sticks all my life ..so it doesnt bother me with constant shifting..
My buddy has a old dodge with a t56 in it, he did the power tour one year...his legs were wore out from clutching thru the small towns with huge pt traffic clogging them up..
Great looking truck

GetterDone,, thx maybe is comparable to the 56 Chevy pickup I had with a granny gear in it

Kipps ..yes thx I would have some tired legs now being older ,, I only leave the place when no work traffic or at noon and that helps no matter what I drive

57Naoco,, thx for the heads up...we do have a Kia Suv that does our grocery run and other things car

Mongo thx to you too,, I remember the 56 pickup and not using first gear hardly ever too

I will back up the converting to hydraulic to make pedal operation easier. Those Z-bar pedal return springs are ridiculous.

Thanks for opinion Nick
What does it consist of to change to hydraulic.. Parts and Money to get it done if I decide to do that?

[geezer#99]

Return spring is not a factor.
Style of pressure plate is what to watch for.
A nice raised finger diaphragm plate is best.
You might have a 3 finger borg and beck in there now. Definetly a left leg abuser.

I have a customer that's a retired GM/Allison engineer that did the durability testing on this trans and I had ask him about using Mobil1 synthetic in it. He told me that once you break it in and change the original fluid - it about stops wearing at all !
