Well since I'm getting tired of having low trans line pressure after it warms up, I think I'm going to get in there and change the PCS myself. Before the shift kit, I was experiencing very slow shifts after it warmed up, and soon after Max Adapt set in causing all gears to slam, even torque converter lockup. The shift kit fixed those 1-3 shifts(and eliminated max adapt), but I want my lockup to be quick as well. I also just want my trans pressure to be correct, bottom line. Lower isn't good. I have looked up many posts on many different sites on how to replace it, most people say it's labor intensive but every explanation I see makes it seem fairly easy. I've dropped subframes a few inches and removed engine/trans mounts, I've removed ball joints to remove CV axles, I've done a trans fluid change and had the confidence to do a shift kit. So basically it doesn't seem like much of a hard job to me. I'll probably spend a day on it though being my first time. Any tips or advice before I order the part and replace it? Like:
1. Anything else I should replace while I've got access to the valve body?
- Side cover gasket?
- TCC solenoid? (Part#: 77942)
- Boost valve? (I have a boost valve from my TransGo shift kit btw)
- 4th clutch hub? (Aftermarket(heat treated) #84860C)
2. Any other things that are hard to do?
3. As far as I know the pcs is visible and replaceable after the side cover is off. I know I have to remove the bolts on the P/S rack to drop the subframe.
4. And how about parts? Should I just get an AcDelco part? It's part#: 10478146 for the 98-02 pcs. I found it for about $31 on amazon.
