I got down to the last load and the tranny began to slip. I am now having trouble getting it to catch 3rd and if it does it lopes down the road. Fluid is good. checked shift and detent linkage...all vacummlines I could see. Made sure tranny line to modulater was clear.tightened edlebrock carb. ...valve covers...tranny pan ....everything seems fine. but I swear it still has a vac leak. Also someone must have leaned on my power booster and broke the large hose fitting on the front side of it.so I sealed it up with some steal epoxy stuff.was broke down as someone had siphoned my gas!!! @#*+x<"_+ if I ever find out who............POW Anyway as of tommorrow I will have no transpertation....Can any one HELP me?

i got a 87 blazer, you can accelerate to 2500 - 3000 rpns and never shifts gears at all . i pulled the tranny and put another ussed one it with very low miles and this is doing the same thing. i checked all the cable the best i know how , i checked the electrical connectoin from the side of the trans to the engine. i removed the wires, i drove it no difference at all . i really need help.
one guy told me to check my tv cable . i have a repair manual but it doenst say much about adjusting it or even checking it


can some one help me please

check to see if any of the transmission cooler lines are crimped all the way up to the radiator , sounds like it is getting hot on you. also if you had a vac leak going to the trans modulator it would probably not shift out of fist gear as I have had that before.
