Chevrolet Repair: slow pull off the line, th drive, tranny problems

Question
Hi there - my 95 k1500 Z71, 5.7 ltr V8   is showing what i think may be signs of tranny problems.
About two months ago i thought i noticed what could best be described as acceleration troubles leaving from a stop light with in town driving. it only happened once and i dismissed the fact that there was no pop in the accelaration off the line. well here we are two months later and i notice the same thing leaving a stop sign and again pulling into my inclined driveway - giving it gas only makes it chug harder as the truck creeps up the hill way too slow to be OK. Not going to try and diagnose this myself but wonder if it could be another tranny problem - owned the truck for about 6 years now and got a tranny rebuild when i bought it. Im ready to take it to the dealership and tell them to go for it - but wanted some knowledge first. HELP?!

Answer
could be but if it an automatic could be something realtivly simple. hmm. just throwing a new tranny on it might not fix it but it might fix it anyhow.. are the fluid levels good? was it a good rebuild?? if it a manual try backing up th drive in reverse, if that goes good, great but still im booged as to why it would do it up an incline and at stoplights.. bad gears?? hear anyhting grinding? noise??  hmm keep me posted i will do some reseach into it... MIND YOU I DONT DO HOMEWORK THAT OFTEN!! so your lucky....
