I did a quick search and didn't see any results so I decided to make a post. I notice a lot of people say they run Automatic trans and some say they prefer them. I know the pro's and con's of automatic and manuals in gas cars and was wondering if everything holds true to diesels. Why don't more people when upgrading transmissions not do a manual switch?
I lot of diesel guys like the autos because you can do a boosted launch... With a manual (5 speed in OBS and 6 speed in SD) You can't build any boost..
Why can't you do a boosted launch with a manual? Simply adjust the clutch so there is not enough friction to move the truck, the push the clutch in, hit the throttle and wait for the green light.
Kinda confusing why you can't do a boosted launch. Plus with an auto doing a boosted launch seems like it would burn up the TC wouldn't it?

That still doesn't answer what I asked, plus with a manual you can hold any gear you want, manual you only have first and second, not to mention the benefits of push starting when your batteries are dead.
You may have less gears but you can still manually shift an auto. I can't imagine that you could push start one of these. You need good power to run the injectors, without the batteries I don't know if it would run push starting it? Never done this, but when the batteries are bad in my truck it runs like ####. If at all...
I think one of the biggest factors for why people like the autos for both racing and towing is that the auto will keep the turbo spooled up between shifts and little to no loss of boost.
I drive nothing but manuals,they are better on fuel and lighter. The main reason i dont stray from them is the control. My father and I have almost the same truck and me shifting down when I want kills tow haul mode for compression braking not using the brakes. As for boosted launch that doesnt bother me, I just use my truck as a truck I dont really race it.
Take a look at the tow ratings between the manuals and autos... Granted, these are Ford's ratings - so who knows what legal factors out-weigh the technical factors.... Regardless, I love my Torqshift.

Try revving your truck up in park or neutral, if you have one.. And see how much boost it builds, about three pounds. If you do that with a clutch your just going to make it slip. You need more than just revving up your engine to build boost. If you don't want to take anybodies advice then don't post... Plain and simple.
I'm just saying that alot of diesel enthusiast like the autos because they can build boost before they take off... Called a boosted launch.
I don't currently own a PSD, but my goal is to get one, riding in a 97' Dodge 1500 right now. Anyway, I'm asking not because I want to throw away everyones advice, I'm trying to understand why it doesn't work. As far as slipping is concerned do you mean the clutch will slip when you let it out, and wont an aftermarket one reduce that? Also you said revving your engine wont build boost, then how do auto's build boost?
Part of why I'm asking questions is so I can build my truck up properly when I do finally have the money to buy one.
I'm not talking about the clutch slipping when you let out I'm talking about while your trying to build boost. Watch this video.
You see him "building boost" he can do that because he has an automatic.. Automatic have torque converters which will allow you put a load on the engine in turn building boost..........Letting you do a boosted launch. With an manual you have to pretty much dump the clutch.
I'm trying to find a video of a 6 speed taking off but I can't right now because they SUCK at taking off.
Thank you for the the video and explaing that the auto puts a load on the engine but how quickly do you run through tc's doing that, I would expect a lot of wear and tear.
This is probably far fetched and I may get laughed at but could you build an exhaust restictor operated by a switch so that more exhaust pressure would be sent through the down pipe instead out the back of the truck to build boost.

:whs: A built tranny generally people get them from BTS, not the only shop, cost about 4500 dollars but will last you forever. But a good valve body and a good tc will keep you going for a while if your not crazy hard on the trans.
I run a manual. I live and drive in mostly rural areas, and have winter conditions from Nov to Apr. I don't drag race, but I have pulled a sled a few times. I like the control I have, being able to shift when I want/need. If I spent more time in high traffic, I'd have an automatic.
I test drove a 6spd sd before I got mine. That was back in 2001. I got mine mildly used. Its a 2000. Ive always owned sticks and when I bought a super duty I said eff that. Never looked back! The autos can be built nowadays to handle/hold the amount of loads you throw at them and I cant imagine having shifted six million times in the 260k miles Ive got on the clock. With a 6speed, just when the boost is coming on you've gotta push that pedal waaaaay over on the left and dump it all. Sounds backwards to me.
Im talking about fun,its no fun to set your right foot down,but it is fun slammin through the gears and revmatching. Automatic is the downfall of mankind and is only for lazy and old people.
I have owned both autos and manual transmissions. In my opinion the auto is the way to go. The manual transmission is "fun" in ways. I did boosted launches with mine, nothing like smelling clutch in the cab trying to do one. Also with loosing boost between shifts, no matter how fast you can shift that needle dives hard. Here is a video of my old SD, it was stock everything besides exh,intake and DP chip at that time. It was a slow truck, my wife's neon could take me up to about 35 mph. The second video is not mine but should give you a good idea on the difference between an auto and a manual. Pick your poison, mine just happens to be an auto
Please excuse the missed shift at 70mph.ointlaugh:
I guess each transmission has it's niche, if you want to hold gears and control shifts go manual, if you want to drag race and have the comfort of not manually shifting get an auto.
You can lock a 4r100 or tqshft into a lower gear as well as lockout the o/d. The only reason that they had the 6speed was because back in the obs days the autos were such sh!t that people bought 5 gears and consequently 6gears when the sdbs came out. End of story.
Tuners made the trucks run better and made the trans behave like it should.
The comment about the auto's being for lazy people is hilarious. I like the fact that it shaves time off of the workday and makes backing easy. Sticks are for cruising around and trying to impress somebody that you know how to 'drive a big rig'.
I know allot of folks on here drive trucks with ZF5 and ZF6 transmissions. A good clutch that will hold, is like an on/off switch, a real PITA when backing a trailer up or in stop and go traffic.
I love a manual tranny.. I just like the control i have over the truck, and i don't mind shifting even in town.. But i love the Auto for "Lazy" driving.. Just get in put in drive and go, no effort needed
