black smoke no power
i got a 93 auto, when i put truck in gear engine will not come off idle and blows soild black smoke. it seems to idle fine in park or neutral and will rev up fine when out of gear. If i get the truck moving runs,shifts, and accelerates normal. acts like its flooding trying to come off of idle in gear.
Do i need new IP? not sure whats going on here

tried that already. thought that turbo may have seized at first but prop spins easy.
can trans boog down motor? i can put truck in gear and floor it with foot on brake and truck can not push thru brake at all and engine will start to die if i hold it too long. If I let off brake truck will roll forward and once it gets moving will acellerate and drive and shift fine. some one mentioned torque converter can the torque converter do this?
thanks

took truck to transmission shop he drove it and said problem is not transmisson, said i needed new turbo.
i still think its tramsmission
in neutral idles at about 750 to 800 put it in gear and idles at about 350, and truck will drive off even up hill without any throttle.
I have another 93 with auto trans, it dosent drop near as much when put in gear and will not roll up hill without throttle. I think i am going to take truck to another trans shop.

It is not an issue with the trans IMO.
You need to look real hard at all the charge-air plumbing from the outlet of the turbo, all the way to the engine.
You may consider pulling the plumbing boots off and physically inspect them for any small holes.
Also look hard at the inter-cooler for cracks/corrosion.
You might consider disconnecting the charge-air plumbing from the turbo as well as where the plumbing connects to the engine's inlet. Plug one end and apply air pressure to the other and then swab a strong soapy solution to everything. Look for the bubbles and correct as needed.

Take it to a different trans shop. You could remove the entire turbo and it would not do what you're describing.
A torque converter turns into a very inefficient fluid coupler when you lose the stator to redirect the fluid. There is no way a small hole in a boot would do what you're saying is happening here.
Take the intake boot off of your other truck and drive it. It will smoke, lose power (all the time, not just on take off) but it wont act like the broken truck does.
The converter is confusing your input shaft. Without the stator working, the the drive hub in the converter doesn't know which way to spin. Once the truck rolls, the input shaft starts rotating in the correct direction because the drive train is connected to it. This is the reason that once it is rolling, you have normal power and driveabilty. If you had a pump or turbo problem, the fact that the truck is rolling wouldn't make a difference.
