James West uses Lucas Transmission Fix 1987 F-250 6.9L diesel

A year ago I got a free truck. My 87 F-250. The man that gave it to me said it had a bad transmission and the motor had no compression. It has the International Harvester 6.9L diesel. A motor I know well (I have 6 of them). I put 7 glow plugs in it and a new starter. The truck fired right up but had a bad lifter tick. I changed the oil and added a bottle of Lucas oil stablizer. The motor ran better and no tick. Well the trany had no oil in it. I filled it with oil. It worked a little but still did not shift right. A bottle of Lucas automatic trany fix did the trick. Then the power steering made noises and leaked. A bottle of lucas power steering stop leak fixed that and, it has less slack in the steering. I tow my 23ft. camper with this truck and have had no problems with it. Thanks to lucas products.
