1st in a ZF5 is not a granny. You need a ZF6 for that. Starting in 2nd justs puts more wear and tear on your clutch. I think it's fair to say if you kill the engine just getting the truck rolling from a stop sign, you probably ought to be using a lower gear.

5 speed or 6 speed.

Zf5 or ZF6. =)

The Low gear on the zf6 is almost identical to first on the zf5.

Most people I know with a zf6 still start in 2nd though, cause 1'st is pretty short still.

Well, there are 2 versions of the zf5. ... hehe.

96-97 had an upgraded version of the zf5. They are both great transmissions, but the extra's on the 47 are a little nicer.

well ill toss in my pennys worth.

i found out that just becuase i have a bid expensive clutch DOES NOT mean you can be doing 4 wheel launch's and burn outs and what not. i dropped a nice dime on a valair clutch and almost exactly a year later i was replacing it with another one. and the one i have id say is a litttttle stronger than a stocker.
word of advance, slip the least amount possible and stay away from high revs when slipping/launching the truck.
if you want the fun stuff save up for a triple disk! lol

When starting at a red light I start in first and I am shifting into third by the time I cross the other side of the intersection.

Starting in second will wear the clutch prematurely.
Same way for me, I limit slippage as much as possible. The topic is takeoff but I just tend to baby my rig. I will punch it in 3rd once in a while to blow the cobwebs out but that's about it. Any sort or premature wear is out of the budget.

if the clutch is locked, and doesn't slip due to wear, you dont have to worry.

But yeah, taking off can be a beotch.

But there are lots of ways to "practice" with a clutch that wont pre-maturely wear it out.
