I have a 93 Cheyenne 1/2 ton, 2wd, 114.000 miles. The transmission works great shifts great, no slippage etc. It does however blow fluid out the overflow vent, I have to add every 75 miles or so. I checked with the tranny shop and they said it needs a complete rebuild, for $1,200 that doesn't male sense to me. If it is shifting great and not slipping why should it need a complete rebuild? Thanks!

Somethings not right if it blows fluid out of the vent. Are you checking hte fluid with it idling in park? If so then the trans is probably going to need a tear-down at minimum to see whats wrong.

Didn't give an answer! I could have gotten that answer at walmart FREE! Of course i'm checking the fluid level with the truck running at operating temperature, in park!

Ron, usually when they blow fluid out it is from overfilling, foaming, heat, the last of which will cause the foaming. Could be the trans is coming apart inside and it has caused a restirction in the cooler, creating excessive heat and thus blowing it out the vent. I have seen them work perfectly right up until they break and dont work at all. I would have it looked at, if it does eventually have a big failure it could damage the case, thus costing you more to fix it
