461 Big Block 700R4 Tranny with about 3 seasons on it..
I am going to a local car show and enjoying the ride. I got on it a few times no issues... Now I am doing about 45 and I get on it, and I see a small cloud of smoke, burning smell (like oil) then my RPMS shoot up... Pull over, I have 1st and 2nd, no 3rd and of course no overdrive, what did I break?
I agree 3-4 clutch pack is a goner a full overhaul is on the menu now,TV cable adjustment is critical on GM and Ford overdrives.If you used the LOKAR TV cable KD-2700 and bracket SRK-4000 the bracket is only held down by one Carb stud they will work loose and change the throttle pressure (BAD design) in any case something has probably caused that adjustment to change and fried the transmission.You might want to consider this upgrade into the rebuild:1987-92 GM 700R4 Constant Pressure Valve Body
Your bracket looks fail-safe, these O.D. transmissions should always be set using a pressure gauge for positive results. Excessive heat is also a common culprit, the stack type transmission coolers that B&M and others offer is cheap insurance and a "must have" for performance or towing applications.
I have a Transmission cooler and a gauge, The gauge was indicating normal operating temperature, however when the incident occurred the temperature indicator shot up into the yellow, however it never hit the red zone....
Now I was also told over on Team Chevelle it's a possibiliy the Gear on the Governor could have caused this issue as well. I will be pulling the governor today, any thoughts?
