Hi, question for you. Because of fuel prices the truck has been sitting more. lol When I do get to drive it though and start and put into drive it takes a while for the truck to go. Is this something that the dealer can fix? Never had a auto trans slip like that before.
thanks

it's a 2004.5 auto 4x4

I think it does that because you converter looses the fluid in it when it sits for a while, and it dosent fill it back up till you put it into gear.

would a different tc fix that? Don't like putting the truck in drive and nothing happening.

Im pretty sure most upgraded valve body fills the t/c when the truck is in park, unlike the stock ones.

Just changing one valve in the VB will address the drain back issue and allow the trans to circulate fluid in drive. While your at it a shift kit is a good addition and will accomplish the same thing.

The simplest way to avoid the problem without spending any money is to just put the truck in neutral right after starting it. That will allow fluid to circulate and fill the converter back up. I usually do this because my trucks sets for a week or two at a time and I just let things get flowing and watch the oil pressure. Once it's up....the trans is usually ready to go. Free and Easy.

What he said. Hit the nail right on the head.

Is it bad for the trans when this happens? Mine does it as well, I'll have to try putting it in neutral next time.

Since these trucks don't pump tranny fluid in park I always idle my truck in neutral.

X3 putting it in neutral first...

Torqueflite has had that problem on some of them since they came out with the thing in 1965. Running it in neutral as was posted is the answer short of spending money on it. Trying to start moving dry will cook the clutches. You can drive it forever without hurting it using neutral to refill the converter. Only takes a couple of seconds.

I see there is a post about shift kits. I have a 2003 3/4 ton two wheel drive auto and interested in the shift kit, some more information on them please

Search it!!
Transgo is very common.
It requires you to remove the valve body, swap/modify things. It will raise pressures and change shift timing.

Just installing a shift kit alone will not allow it to pump in park. IIRC you have to modify the valve body before it will pump fluid in Park.
