If I had any! My '95 F-150 4X4 trailer towing w/ 5.0L.

I replaced the 4R70W with a rebuild at 198K. Not long, maybe 3 months the OD light starts flashing and the only code shows excessive slip of the torque converter. The rebuild shop advises Trans Guard additive and two of those little tubes makes it operate like a new unit. After another couple of months, same thing so they send me another TC. BTW, with the tranny switch I used Mercon V . Second TC installed I use Mobil 1 ATF and on my merry way I go.

2 months later, same issue. In goes 2 tubes of Trans Guard and all is well for 3 weeks then same issue, excessive slip and limp home mode!

I am tapped out. I sure wish that I would have sank all the $'s I'm out now into the original transmission but that is spilt milk.

I am guessing the TC clutch surface has developed a glaze and right now I am looking for a shade tree mechanic fix to add something to the fluid that could break the glaze. I know I can't go too wild because of the bonding of band surfaces could be compromised.

Any ideas? Would a short run of Toluol, acetone, 111 Trichloroethane, Panda ****, anything gonna help this every day Joe fix his old love??

The preventive maintenance on this truck is done. No vacuum leaks, all engine control sensors, solenoids, etc are new. New off road Y-Pipe.
This truck purrs! I change the Mobile 1 engine oil every 10K and it doesn't use a drop, other than this damn TC issue !!!!!

As usual, I cast myself onto the mercies of the community for any thoughts??

Not here often, excuse my haphazard postings. Could someone delete the other two?

 

You're posting in the wrong forum, this is for 1973/79 F100 and larger series trucks.

You want the 1987/96 F150 and larger series truck forum.

 

Move requested.

 

PLEASE NOTE: This posting is now in transmissions, I will pursue a moderator to quell the angst!

 

Not a problem, you will just get more accurate info in the right forum.
