i just finished changing the cam in my 76 l 48 automatic. i put a a mild cam from summit i beleive it was a 1103? anyway i also went with the true duals. i took the car out after we broke in the cam and it sort of make a weird sound once or twice not sure were the sound came from? so i just took the car out i got 3 blocks i nailed it it made that sound and the tranny stopped working? so i pulled over i gave it alittle gas and car moved real slow give it gas rpms go up car wont move pulled over again and took off slow so i got it back home? my tranny before the cam shifted right on real smooth and ideas what could be happenig oh i did take off my tranny pan replace the fliuld and filter??? thanks in advance tim bob

What does the trans fluid look like? If its burned, its time for a trans rebuild.

Perhaps its just low on fluid.

my 91 dodge has trans problems n i was told that since it had 100k on it n still the same fluid that changin the fluid n filter could cause more damage. i didn't listen to im n changed it anyways n it didn't help but didn't make things worse. no idea if this guy was right or wrong but it might mean somethin to somebody.
i'd check the level immediately. also if i'm not mistaken it takes more fluid to shift into reverse so that may be a good test. i'm not the greatest at diagnosin transmissions but i can rebuild the old THMs easily.
