I bought 79 Ford truck from a young kid that worked for me. His father was the original owner and gave it to him when he was 15 back home in MT. He had moved to Portland, Or after finishing school and worked for me for some time. The gas was killing him so he purchased a newer Toyota pickup, std cab 4x4 what most of us had for our first truck. He wanted to sell his Ford F-250 but the had told me the trans was slipping. So I had a trans tech look at it and verified that it did. I took it around the block and when it locked up in 3rd it would slip forever. But after driving it and really looking at it I was amazed at the condition in and out. Had 77k original miles and had nice options So I bought it and would worry about putting a tranny in it later. I was just helping this kid out and I liked the truck...Weeks later I was talking with a vendor and he recomended a product called "Trans-X" It comes in a can like the old Oil cans. Read the direction! i did not and poored the whole can into the the tranny and within 5 miles It would power brake and smoke the tires and the shift points were crisp and hard with your foot in it. i was amazed by what had happen,. I am selling 4k trans for these issues and a $5.00 wonder car fixed my issues...........Simply amazing! I have also used it in leaking P/S systems. What is does is soften the bands, seals and friction plates. the have a 100% 5 mile guarantee and recomend it in all hydraulic systems.
