What you're trying to accomplish here is the best compromise between clutch life and drivetrain life and smooth operation. If you let the clutch out totally and then give it gas, it's very hard to give it gas in increments small enough to not make the vehicle "lurch" back and forth. This is hard on u-joints/cv joints and other drivetrain components. And it makes you look like you don't know what you're doing because everyone sees the car lurching and stalling if you're going up a hill when you take off. The other end of the spectrum is if you give it about 2,000 rpm's worth of gas and "ride" the clutch out very slowly. This makes for very smooth take-off's, but very hard on the clutch itself. You just have to find a happy medium between the two. Try and keep the engine rpm's as low as possible while still getting a smooth and seamless take off, and get off the clutch as soon as possible while still getting the same smooth take off. This all comes with time and practice and you WILL get the hang of it in no time!

It may not be the tranny...
I had an 88 ford van , the tranny started knocking and bucking and I was sure I needed a new one.
I went to the local tranny guy and he drove it down the street and said " this tranny is fine ! "
I wanted to believe him but was comepletly sceptical and all untill I did what he said ( mind you I've worked on my many old used cars myself for like 20 years now and know cars pretty well, but I am not a tranny guy.
He said it wasn't the tranny at all, just was the engine bucking and it needed a tune up.
I got new plugs and wires and guess what, no more bucking and kickin from the tranny ! HA !
SO - Take it to the old transmission guy in town.
They will usually have old time experience with old time trannys and beable to give you some free advice.

Check the u-joints and carrier bearing. If it's an extended cab or long bed, it probably has a carrier bearing. U-joints are simple to replace if they are bad. Also you might want to check the clutch fork if the u-joints or carrier bearing are alright. Some people have a habit of riding with their hand on the shifter, and this can wear out the fork. Also check the clutch ball and release bearing.

Get under the truck and twist the drive shaft back and forth. You may need new uv joints. Ther shouldnt much play if any.

Sounds like universal joints......take the drive shaft and twist it back and forth.Should not be any play in it...if so take it to mechanic and have them to replace them .If you do not replace correctly you can get them out of time and can cause big problems later.
