I have a 2003 short cab f150, I bought it with 110,000 mile it now have 132,000 when I go to jiffy lube they tell me I should get the transmission flush, I need to know if this is going to cause me proplem if I do it, because of the high miles my truck have....any help is apreciated

 

I was going to get one for my 04 Screw at 100,000 but im not sure if I will anymore, I've heard of people getting a tranny flush one day and their trucks stopping dead the next. Sometimes on a vehicle that has not been flushed before with high miles a flush will loosen up particles and junk that can get stuck when all is said and done. The local transmission shop suggested I just replace some of the fluid and do a filter change, it costs about the same and changes about 1/3 to 1/2 of the fluid. If the fluid looks good and the tranny feels good it might not be worth the risk, the harsh detergents in the new fluids can eat the enamel built up by the old fluid, leading to leaks. Tranny's are sensitive machines and not easy to service or fix for the regular joe schmo. Im going to wait it out on my truck because everything is checking out now, but in the end its really up to you and how you see it...

 

no.. i wouldnt flush it.. if it were mine i would drop pan and change filter and replace pan gasket.. be sure to clean pan and magnet very good...and be sure not to over tighten the trans pan... just my 2 cents
