Anti-drainback in tranny and front pump

[orion_134]

I notice when I start my truck up after a day of sitting, it takes a little while to build up pressure to back out of the parking spot. I am going to be replacing the tc and vb this week and I am wondering if the the anti-drainback valve is something I can check/service while I have the vb out and the tranny down (where is it located)? Also, should I replace the front pump while I have the tranny out?
I need to know this guys, the stuff is on the way to me and it's almost down to the wire...time to install.
Thanks,
Jesse
