Transmission is on it's way out...

[GreenF350]

Well, I know these transmissions (4r100's) are not known to be the greatest but just wondering if anyone thought it was worth changing the fluid and filter (supposedly done right before I bought it and the fluid is in pretty darn good shape). Yesterday I left home and thought that it seemed to be hanging between shifts just a fraction of a second. I was on the way to my "outlaws" for Easter and decided to press on. When I got there I checked the fluid and all seemed well. On the way home it seemed to be hanging between gears longer and then "slamming" into gear. I was trying to drive as nice as possible and once it was in gear it seemed solid, just wasn't liking the shifts. As I pulled off the interstate and went to turn onto the surface road it was acting like it was in neutral until the RPM's came up. It does this from a stop now every time, regardless of whether it is locked in 1 or in D. Oh yeah, and the truck has 138,000mi on it and the original trans. Anyone think this transmission can be saved? If not Suncoast is local to me, I am planning on going down and checking with them tomorrow. Anyone ever heard anything bad about their parts or service? Sorry it's so long and thanks for the help.

i have a 96er with a stock tranny. i go 15k - 20k miles between oil changes. i have heard it's best to do a complete flush every 20k.

AMSOIL ATF is a stable formulation that lasts longer in service than conventional ATFs. It maintains its viscosity, friction and lubricating properties for extended periods of time, even under severe conditions. AMSOIL ATF maximizes transmission performance and service life while
reducing maintenance costs through longer drain intervals.

SERVICE LIFE
AMSOIL Synthetic Automatic Transmission Fluid is recommended for use up to 50,000 miles under severe service* and up to 100,000 miles under normal service* or according to the vehicle manufacturer recommended intervals, whichever is longer.

good afternoon
my 2001 F350 dually w/111,000 semi easy miles has started to slip in first, when cold it works fine, sometimes when warm it will not go into first and start out. When I shift it manually into low/ first I feel it go into gear and start out. I went to my local trans shop and had it scanned, it was clear. I am looking at $2400 for a bench rebuild but looking for an alternate fix like a heavier duty trans or if it could be a " sensor " or something else.
Oh and for amsoil guy I am in the Amsoil hometown and I am on the test oil program and they just put the new style bypass filter system on...thanks
