Transmition problems

I have a '91 E-350 with the diesel motor. Last week the trans. started slipping while in drive. I changed the filter and put in some additive. Stared running better for a few days. Yesterday while driving down a highway it started acting up again. Slipping real bad and the OD button was blinking. What should I do? I know it's going to be a costly repair.

Most likely the TPS is either bad or misadjusted, that would cause this.

Thanks ModMech, What is the TPS?

Throttle position sensor. It is located on the driver's side of the injection pump, and is accessable from the front with the air inlet bellows removed.
