I have a 1981 2WD GMC Sierra Classic automatic and i just got the engine replaced yesterday with a 350. When i drive the vehicle, it seems like its not shifting into second gear. The engine revs really high and just stays in 1st gear. Eventually after awhile the truck makes a clunking noise and lunges forward and finally switching into second, but stays in second. Before this it just reved really high and changed, but after i filled up the tranny fluid after it was very low, this problem was produced.
I know for a fact that there is no leaking either. Where could the fluid gone ?:P
What ya think the problem is?
