slippage at low speed

[sailorkaplan]

I bought this 2001 SCREW last year 5.4 4r70, it had 76000 mi. I immediately had the tranny flushed, now I have 94000 on it and when I am pulling out of a parking lot turning right it seems like the engine revs a little between 1st and 2nd gear. Did anyone else ever had this sort of problem?

i have a 97 with a 4r70w and it started slipping really bad between shifts. i put a bottle of lucas transmission additive and it fixed the problem imediately.
then i took the whole thing one step further and installed a b&m shift kit in it and now i have no slipping at all and there is no pause at all between shifts.

I 2 had the same problem with my 97 f150. I took it into the dealer and they did something with the computer. It shifted better untill i put a different transmission in after alittle accident i had. This "new" transmission slips even worse, especially if i have to punch it to get out into traffic. The dealer said they can't do anything with it besides replace it.
Where do you get that lucas transmission additive? and where can i see the b&m shift kit?

Thanks

i bought the lucas stuff at canadian tire........ i dont think they have a store in wisconsin. i think ive seen the stuff at napa though. the best way to go would probably to install a stage one shift kit in it (cheaper than you'd think) but the lucas stuff will give you instant results.
