hewlett2002000 · 03-27-2007, 11:58 PM

ok yall im setting my body on a 84 frame. my truck currently has the 4-spd but im giving serious thought to using a THM350 i have here. i mean when your on a date and you have to say "lemme take my hand off your leg so i can shift honey" it gets a bit old. lemme know what you think.

I used to drive nothing but sticks. Now driving my '68 with a manual 3 speed (3 on the tree). In traffic or especially when I'm stopped on a steep incline with another driver that just has to be right on my ass...or in those RARE situations where you must bring food and drink into your pride and joy (so you can eat on the run to make up time) and then have to shift and spill the fries....I'm wishing I had an auto.

I love my 4spd. If I had to choose between it and a auto with overdrive it would be tougher. The granny low is great off road and I prefer a stick for the trails.

If I had a 2wd, I'd deffinately prefer the auto, even without the OD.

Eliasj123 · 03-28-2007, 01:21 PM

I love my auto because I can eat, talk on the phone, change the radio, and play the air drums, all without having to be interrupted by shifting..

But that's just me..

Nuthin like holding it to the floor and letting the tranny bark through the gears for ya. It's bad enough to have no cup holder with an auto... Only manual I'd consider would be a 5 or 6 speed on a 2wd. 4wd I can see the justification for the stick, but with your truck/options I'd go with the auto.

hewlett2002000 · 05-18-2007, 01:07 PM

ok yall, i got a question??? will i get as good of performance with the th350 as i do now with my 4-spd? i know thats probably a stupid question but thats what im concerned about.
thanks,
John

gulfcoast66 · 05-18-2007, 02:39 PM

whats up hewlett2, is that a muncie or a saginaw 4 speed? i got a 3 looking for more gears for my truck, i love down shifting to a red light in town!!! its nothing like poppin that clutch !!!!

hewlett2002000 · 05-18-2007, 03:38 PM

saginaw i believe.

*trkklr77* · 05-18-2007, 05:50 PM

which model 4 speed though, 465,420,m20/21/22........................????

if its a granny gear 465/420 dump it.

i would LOVE to have a car/race style 4spd. the only reason i have a auto 400 now is so my woman would sit next to me, she doesnt seem to interested in that anymore so im looking for one.

If you have a 420/465 your truck should be much faster with the auto. My 420 takes forever to shift. At least it's notchy and the shifter has a super long throw

Volvo_Matt · 05-19-2007, 01:27 AM

If this is your daily driver and you have to sit in grid-locked traffic for hours at a time, the auto is your choice....
I have an M-21 4spd in my '63 and there's nothing better than shifting gears and popping the clutch....but that is my weekend driver

hewlett2002000 · 05-19-2007, 01:28 AM

ok yall, how can i tell which model? i would love to know but ive yet to find a identification manual online that helped me much. if needed i can take pictures. now would be a good time to look cause the truck is up on jack stands so i could see real good under there.
thanks,
John

hewlett2002000 · 05-19-2007, 01:32 AM

well this is my (soon to be) daily driver, and well, like i said up top its a pain on dates, and when you need to flip somebody off for riding your ass. which reminds me, my buddy was pissed the other day and somebody started riding his ass, so he hit the e-brake then let off real quick!!, they stayed 2 car lengths behind him the rest of the way!!! lol

An M-21 is more of a muscle car tranny, and shifts much better than the "truck" four speeds with the granny low. If the tranny is original, I think it should be a 420. Reverse is left and down on my 420, I'm not sure about the 465, but I know it's different.

hewlett2002000 · 05-19-2007, 02:12 AM

mine is left then up for reverse, then center up, is first, down second, right up third, down right fourth.

19GMC63 · 05-19-2007, 12:11 PM

sounds like a 420, the SM-465 has reverse to the right, then down.

I have the 465, and its terrible. I've been looking for a muncie car four speed, but they're just so darn expensive.

62 short step · 05-19-2007, 01:00 PM

The reverse on my sm 420 is left and down, for now. Until I put the th350 in its place!!!
