I have a 98 xlt 2wd 5.0 with 294k, i believe this is where i need to be

My 98 XLT 5.0 4 speed auto boggs down after shifting into OD...now if Im on the gas it wont bogg but if Im just cruising from a slow speed it will bogg at the end of 3rd gear and into OD...now ive replaced every sensor you can think of on it except for the crankshaft sensor. You name it, its probably new on this thing. Last night I bought connector cleaner and cleaned all the connectors thoroughly. Especially the one above the plantum with the 10mm bolt. That didnt change anything surprisingly.
I just cant seem to find the problem
The only thing I know to do next is the crankshaft sensor then onto the transmission soleniod..is there anything else I can check or replace before I open up my tranny?

Welcome to the forum. Do you have a CEL on? If you do you need to pull codes before you just start replacing parts.

Thank you
Yes ..i have pulled the codes around 10 times and I replaced the parts for each code. As far as my knowledge..they went away but came back..but they are brand new parts Im still bogging down
All new vacuum lines as well
I dont know what else to do besides the soleniod or crankshaft sensor
