Transmission Help

[rescueblazer]

Ok, i have a 1989 k5 blazer with the 6.2l and 700r4. Its sittin up on 33's. I had the transmission rebuilt by a "mechanic" and when it went out less than 2 months later his shop was closed with no trace of him ever exisiting. ( i know i should of used a more repetable shop but due to budget...i got what i payed for.) I use my truck for search and rescue and some moderate towing. I was on the way home and it acted like it was didnt want to shift out of 1st. I hopped out and realized it was low on fluid i poured some in the dipstick and white smoke come up the tube and out of that funnell...Now it just acts like its reallly low on fluid but its full....Is it time for a complete rebuild or what....please help. Or what are my other options on a tranny swap.

pump could be bad if the fluid level doesnt change. find a reputable shop that gives you a warranty. stay away from AAMCO.

If you plan on putting bigger tires on it, more power and driving it harder, then I'd suggest a swap to another transmission.

I know the 700R4 is better and can be built to handle a lot of power, I ended up opting for a built TH350 to put in place of the dead 700R4 in my 83 diesel Jimmy.

If the fluid is not burnt, then try stomping on the accelerator pedal fairly hard with the engine off. Do this a few times to free up a sticky throttle valve in the transmission. It happened to me before but only after the first time I tried to adjust my TV cable. I did this a few times over a few days and didn't have trouble with it ever again. Hopefully that helps.
