truck jumps out of reverse and back in...

[speedracer1000]

well recently i did injectors turbo fuel system all that stuff and about 1k miles later i noticed the other day at the gas station i went to back up reverse hesitated for a sec then kinda went in hard, seemed like it went into nuetral for a sec then back into reverse, and it all happens like within a few seconds, drives perfectly fine, stock tranny with 148k on it, new fluid and filters about 10k miles ago. it was last week wen i first noticed it, and it wont do it when it cold but almost everytime i go to back up after its been run a ways itll do this.. im thinking possibly a sticking solenoid and it prob wouldnt be a bad idea to upgrade/replace all of em, after all they are the original ones... just wanted to get some opinions about this issue.
