Hey guys. Was curious about a big torque converter question.
I think, the tc is going bad in my 92 grand marquis. Might still be a misfire but no engine light on.
Car often gets warm then starts bucking like a bronko back and forth (like pulling a fold out table across the floor, just more violent) and the engine feels like it isn't getting anywhere. Often will rev high before it shifts from neutral to first. Does this in reverse too, pretty much any gear in low revs.
So My thought was torque converter clutch, but wanted your thoughts before I get a new one. Basically the car has many miles on it, was used and the other owner from the looks of the fluid never changed it (his fluid was dark dark red, couldn't tell if it smelled off, but certainly looks AWFUL, apparently when I called him up he left the car sitting for 2 years, after it has 280,000 miles / 350,000 km on it.), I've yet to put in a new filter but when I changed it for synthetic fluid the problem got worse (bottle said it was compatible for mercon and mercon V, my tranny uses mercon) I also tried lucas no slip no leaks additive but...does nothing really. Im reluctant to drive anywhere and when I do have to be really easy on the accelerator, especially up hill, otherwise once it shift it will immediately be bucking it's way through 1st then 2nd, where at higher revs it feels like it catches and is okay for a while, but Im afraid Im doing terrible tranny / tc damage.
I was TOLD by a mechanic that one way to get more life out of it (which I need to look for a newer car and to go to work the next while) is to APPARENTLY add differential fluid to the ATF and that will help smooth out / remove those jerks. Could it be a transmission or torque converter control solenoid, broken cv joint, misfire (just plugs) or even the dirty clogged filter keeping back pressure as well? I don't hear much as far as noise, seems normal, but pretty much intense forward backward jerking, and feels like it isn't side to side, front to back for sure, bottom of the vehicle feels like it's a thumping demon trying to get out. Only in gear shift, low revs, any gear, under acceleration.
Will that work? I've found absolutely no info about it online, any advice or help is greatly appreciated, student budgets and all. Thank you anyone and everyone.
