i have a 1995 chevy cheyenne 5.0 with 4L60E with 205000, i bought it a year ago and drove great up till 6 months ago, when you started to press the throttle it would bog down but it would go if you pumped the throttle or down shift. i changed the fluid and filter and it was a little dirty but no shavings, it stayed the same then i replaced the 1-2 & 3-4 shift solenoids, now when some times you first start its fine but after the first stop it bogs down like before but some times it drives great.

i have also replaced the battery and cleaned all the groundings and cables to the battery and replaced the throttle position sensor

and there isnt any codes it come up
