Don't waste your money, I took my pick up to running perfectly smooth, no vibration or grinding and clunking noise, to have 3rd and 4th gear rebuilt. Now it vibrates terrible, very bad at interstate speed and clunking and grinding very noticeable at low speeds, they say it's not there fault and get off there property, no one year warranty. They do poor work and then say the problems are not there work and where already there, that is there lying way to take your money and void the warranty and give you back your vehicle needing to repair there lying work!! Now, less than three months later transmission totally failed. I would not trust them to do anything else on my pickup. I had to buy another rebuilt transmission because they ruined mine. It cost me another $1650 to replace the transmission best ruined, now best transmission wants to sue me for writing a bad review, everything I said I can prove and is the truth. Mark knows his son is responsible for screwing my transmission up, he has chosen to cheat me out of a refund because I will not let them do no more damage to my pickup.He is not a member of the Better Business Bureau for a reason!! I took my pick up to Belle Tire to find out what the clunking noise was, Mark bent my right rear axle with transmission shifting gears while going road speed, probably from 4th to 1st than lied about the noise. Liar and cheater making excuses about his sorry work. They don't deserve to get even one star.
