Another possible trans issue?

[mike561]

So until i can get over to a trans shop, is it ok to leave the tcc disabled? or will i risk overheating the trans and causing dammage?

With the TCC disabled, it probably wouldn't overheat, but it will run hotter on longer trips.

ok i might leave it in tact then. what am i looking at if i decide to replace the solenoid dyi, is it a big job? any instructions or pics would be helpful

when I used my vehicle to tow 4,ooolb boat I installed the tcc disable switch ..this was done at the brake switch ,where the tcc wires are located...this was done to reduce transmission shifting and heat....this worked excellant as my transmission never needed repairs....you will use more fuel though as the engine will turn more rpm's...

since you have this bogging down problem I would suspect the engine....is the problem....you must extract the DTC and then this may help find what's not working correctly with the engine....

your transmission 700r4 1984 is not the best vintage for sure...there is a govenor gear made of plastic in their that caused many failures...this transmisson needs a transmission cooler and frequent fluid/filter changes if you expect no problems with it....

I dont think it could be an engine problem since when i press the brake i feel the tcc release and it accelerates normal again as it should

with the TCC engaged you have removed any slippage with in the transmission,,,,at about 42 mph with a light throttle this should engage...If this causes a hesitation then this goes to the engine,,,,usually spark/distributor/plug problems....this could also be other problems though..may be a vacuum leak...or low compression,,,spark plug loose plugged cat converter,,,,,
