Those crawling with SM465, check in please...

Do you run a 465 and crawl/trail run?

i had the sister four speed ( 420 ) in a jeep and i loved it but the third pedel was a PIA never got the hang of it and this was in a jeep the pedal are practally on top of each other, but i took a bicycle break cable and hooked it to my throttle and the other end to the stick ( shifter ) and after that it was like driving an auto on sharp inclines. i am building a rockwell buggy now and will run and auto in that rig, jason.
 
I have had a stick shift in every 4x4 I have owned and love them !

My Blazer has a 465 in it along with a WMS 3.1 geared 203 range box ORD Doubler and 5.86's in the axles.
I understand the need for some folks to have an auto tranny in trail rigs but I like the crawl at idle style of wheeling that a manual tranny can give with proper gearing.

For what I have into my hydro 465 setup I could've built a stout 700R4 with a full reverse manual valvebody. I think the two are comparable in longevity if you run a good cooler on the 700R4.

I mean, I ended up buying all new clutch, flywheel, clutch fork, slave cylinder, master cylinder, hydralic hose, clutch fork rubber boot, and pads for the pedals (were missing). And I'll end up replacing the bellhousing someday because it's spiderwebbed. I got a good deal on the transmission/transfer case... but the transfer case had a cracked tailhousing. All said and done I have like $850 into it... and that's not rebuilding the 465 or the 208.

With my 7 cylinder TBI305 it still makes enough power at idle in low range first gear (64:1 crawl) that the IAC valve will get me up most stuff. If I had better gears (88:1 crawl) it'd be almost too slow. The nice thing is that I'd virtually never use that pesky unsychronized first gear.

Which brings me to my complaint about the 465. It is a long throw wide ratio transmission with an unsychronized first and reverse gear. Something like the 4500 or 5600 would be nice... still have a good first gear... yet everything is synchronized. Just like an automatic transmission, there is no shifting the gears from forward to reverse while under power/tires moving. The 465 just plain won't let you and the auto will probably blow up a sprag.
 
I wouldn't go any other route. have an 87 with 465 and bought an 77 with th350 to change to auto. Took them both out and it changed my mind completely about going to the auto. Sold the auto setup in the 77 and never looked back. Like some of the others were saying I hardly ever use low range. first gear in high range with no throttle will pull you up a small hill (slowly). If too steep 2nd or 3rd gear in low range will do it. I love it.
 
Damnit once again Rene beat me to a post and said pretty much exactly what I want to say.

I had a th350 in my K5 and swapped it out to an SM465 and was immediately in love with it. Now I never have the thought "what if my tranny goes tits up out on the trail" Just not something you have to think about with a 465. I like the torque multiplication of a torque converter, just keep mashing the pedal down and it keeps adding power, but its even cooler to just throw it in gear, let out the clutch and idle along. I swapped out my 350 gasser for a 6.2 diesel. In high range with 39 inch boggers I can throw the 465 in first and idle over most trail obstacles without ever touching the throttle.

The last straw with my th350 was when I tore a transmission line on the trail and spewed ATF all over my exaust manifolds and the transmission quit pulling. I thought damnit im going to put a transmission in here that dosn't need a hydraulic pump to build pressure to make it go.

Why SM465s rule by Robert79k5
1. Dosn't require a cooler
2. dosn't reqire lines to run from a cooler to the transmission.
3. will still drive the vehicle even without a drop of fluid in it.
4. more efficient as mechanical energy isnt converted to heat in a torque converter because there is no torque converter.
5. Flat out tougher... no clutch packs or pumps to wear out.
6. Simplier.. no valve bodies, filters, solonoids, throttle cables, plungers, check valves etc...
7. If the unthinkable happens and your SM465 does go haywire out on the trail you can just unbolt the top, pull the shifter/fork assembly out and pretty much get to everything you need right there in the truck. you can even shift it with a screw driver if you need to.


Whats funny is I decided to fix up the Blazer and make it nice so now im building a lightweight trail beater and its going to run a TH350 auto. But thats a story for another thread. :crazy:

Tim's truck has a Quadrajet on it. i have tried several times to get him to rape the 87 R30 sitting in his yard of the TBI, but he refuses for some reason. :crazy:

he's running 39.5s, not 38s.

my bad....... :doah:

My point was to explain large(37-39's) tires with 4.10's worked with a 465 great. :D

Yea, me too, I forgot to say my truck is a diesel. Don't need to touch the go pedal to get out of the clutch, just brake and clutch.

A 6.2/465 combo is hard to beat. You don't even have to know how to drive a stick and you can drive it :laugh:

lucky it didn't catch fire, or did it?
 
I went from 700 to hydro 465 and love it. the only downside for me is that before I could go on a long road trip if I needed to becuase of overdive. now I am running 3 grand if I go over 65 with 456's and 35's.
but the low gearing on the trail is awsome.
 
Bone stock 350, SM465, NP208, 4:10's, 35's, '84 Burb.
LOVE IT!!!!!! Crawls GREAT, 1/2 the time when I'm doing hill climbs I don't even need to use the gas, just let it idle :bow: :bow: I have not put a hand throtle in this truck 'caus I DON'T NEED IT :eek1:
I wheeled autos only for years, but after this truck I would NEVER go back :wink1:
 
I have swapped out automatics for 465's in the past with no regrets. I currently run a 465 with 5:13's and 39" swampers and it crawls pretty good (454 tbi doing the pulling). I have considered an NV4500 but subscribe to the KISS theory for a vehicle that could potentially leave you stranded far from civilization. You can't hardly swing a cat in many of this country's back yards without it hitting some old Chevy parts. Need another 465? Not only are they common, but easy to put in. :D

That's what I don't like about it...the low gearing is awesome, but in some situations I have to stop while on a steep incline, then let the clutch out and push the gas while holding the brake down :doah: Usually i don't move backwards, but on some obstacles that small amount of movement was enough to mess my line up.

My bud has a Yota with a Marlin Crawler and it is so low, once you pull the clutch out you don't look back.

I am sure the doubler would be tha same way.

try letting the clutch out in idle, then move foot from brake to gas. Granny low in low range at idle has always been enough to get mine moving. (3.08's - 32's)
 
I've been through a th350/203 and a th400/208 setup in my truck. Broke both the auto's. I'll never have another one.

Now I've got the 465 with doubler and 5.13's. All the way down in double low, as long as the motor is running, nothing will stop the tires from turing. As for the starting stoping on a hill and 3 pedal/goofy foot non-sense, 99.9% of the time, I start it in gear. It starts just as easy in gear as it does out, and at 134:1 crawl, the starter isn't workin real hard. ;)
 
465/205 crawler checkin in..

I ran a th350/205 for about 6 years... smoked it one too many times and i decided i'd give the 465/205 a go since it was the same dimensions and my d-shafts wouldn't have to be changed. plus i could always rebuild the th350 and go back to an auto if i ever wanted.. Its just taken me a bit of stalling and playing with it to learn how to really drive it good.
I had a custom clutch built for my application by superior friction clutches in san jose, and i also retro fitted a hydro clutch setup onto my blazer.
For trails and rock crawling i'm real happy with the 465. in granny low 4 low, i'll just turn up the idle screw on my tpi until its at about 1200-1400 rpms, and then i don't even have to touch the gas. :wink1: i couldn't imagine what another 2:1 t-case would do! :crazy: I might still do a line lock just for good measure.
Only thing i'll miss is the fast shifting when i'm in the mud or racing up the sand dunes. other than that, for rock crawling and slow trails the 465 just rocks. Even gets slightly better gas milage than the auto.
 
I run one with a 208 , 14 bolt ff 4.11 gears and 34inch tires. I love mine. sounds like your gear/tiresize makes sense. go for it. Cary
 
since getting my new truck with 465/205, I'll never run auto again. Off road with my '73 is ALL brakes, I hate it. Going up hills is easy, down is scary. I'm on the hunt for a 465 to swap in there :-) Around town is fun though, esepcially in traffic, hate the clutch there
