My truck only has 74,000. mile on it and I haven't pulled any
heavy loads.
While on vacation my truck was fine till I got fuel then when I got back on the hwy it would shift up but 3k RPM's at 50 MPH. The only place I could find that would do the filter and fluid work was Jiffy Lube. It was $134 for them to pull the pan and change the filter, flush the system and put it back together (with me watching like a hawk). It did not improve anything

My thoughts are take it to a trany shop and have them dig into it but be prepared for a $3K+ bill. It could be as simple as the filter and you can do it yourself but by taking it to a trany shop if it's more they will catch it instead of you being out the $45 for the filter and $25 for the 17 quarts of fluid.
Just for reference my 02 CC SRW has 76k on it and the trany went 11 days ago now :-(
Are the auto-trannys that weak in our trucks? Is it just the E40D ( I think thats right )? What year models have the E40D? When ( if ) mine goes I will probably drop a manual in it, but Im hoping that doesnt happen anytime soon.
The E40D is on the pre-99 trucks, the 4R100 is on the 99 and later. They are almost the same trans.
Stock, they are the weak link, not because it is a bad design, but because the bean-counters demanded certain items in the trans needed to be made more cheaply.
If you pay someone to do a PROPER rebuild with upgraded components, it will not cost that much more than a stock rebuild - if you compare the price to what a stealership charges.
A PROPER rebuild with upgraded components turns the 4R100 into a very strong,. very reliable tranny. In fact, according to a couple of high performance parts distributors, a modified 4R100 will take a higher horsepower load than the stock 6-speed manual - although if you keep the power under 400hp, I'd guess the manual would still be more reliable.
I told one in particular that if my 4R100 died, I'd replace it with a manual. He said he'd be happy to trade me a 6-speed for a broken 4R100 - as long as it was rebuildable.
