Transmission problem
1997 Chevy Venture 6 cyl Automatic 141000 miles

I recently had the engine in my 1997 Chev Venture rebuilt because of a broken camshaft. The original engine block could not be used, so a different engine block was used for this rebuild. On the day I picked-up the car, there were transmission problems, where there were none before. The transmission now slips between 1st and 2nd gears. It seems to slip more in the morning, after parked for awhile, or during cooler temperatures. Following rebuilding the engine, the car seems more sluggish and doesn't have the acceleration power it had before. From stand still, if acceleration is slow and smooth, the transmission will often shift from 1st to 2nd okay, but if acceleration is at a greater rate (e.G. Accelerating to freeway speeds on an onramp) slippage occurs consistently. When this happens, letting off the gas pedal for 1-2 seconds oftens allows the shifting from 1st to 2nd gear. The slippage seems to be slightly worse traveling up an incline. What factors might be involved that would cause transmission problems, following the rebuilding of an engine, when there were no transmission problems before? What could be happening? Any thoughts on this would be greatly appreciated!

Low fluid level will cause this.
