Quote from: "Crosley"Quote from: "MIC"i have a 1990 chevy c1500. recently i sprang a tranny leak (lines to cooler) i fixed the leak and when refilled with fuild i found i lost my 3rd and 4th gear. originally i thought i had a turbo350 but later found i have a 700r4. so i buy a 700r4 from a private individual, i install the tranny and when doing an opp test in the garage (axle on stands) the tranny does nothing when put into any of the drive gears. sll fluid levels are correct and installation was correct. what could be my issues?
Did you reuse your converter? Or the converter with the used tranny? Was it a used or rebuilt replacement tranny? ... This could be a mismatch of converter to tranny input shaft splines
possible you broke the pump on install? Converter not fully installed into the tranny?
Have you verified tranny pressure? Loosen a cooler line while the engine is running?
Shift linkage hooked up correctly?
i did reuse the converter. i was told that the tranny was an original from an earlier model car. the guy made sure to point out the new front and rear oil seals and it was painted. the converter was fully installed on tranny shaft and lined up perfectly. i did not verify pressure of any of the lines. i now have the tranny out of the truck sitting on a motor stand. when i dismounted the tranny and disconnected the cooling lines nothing came out, not even a drip and i ran it i know long enough for something to get cycled through the cooling lines. shift linkages hooked up correctly
