Been talking to TSM1 about this already this morning and thought I would get a little more input.
TF 727
I rebuilt my tranny a few months ago, everything but the valve body. I let a shop do that.
It runs great, after I rebuilt it a couple times. <g>
Only problem is that when it gets warm, (not hot, but warmer than normal operating temps) I get a delayed shift into drive from neutral. I have to give it an extra 500 or so of RPM, then it goes into gear nice and solid.
My local tranny shop that did my valve body tells me that a shift kit will not address this problem. The shift kits do a couple things. One is give you instant manual control over what gear you are in (want 1st gear doing 60 down the freeway, here you go) second is they charge the converter in park. This lets you check your fluid levels with the truck in park,instead of having to be in neutral. It also means that while you are sitting in your driveway letting your engine warm up, the tranny is pumping your converter up at the same time, so when you shift into reverse or drive, you have full pressure in the converter, and don't get the morning sluggishness. The third thing the shift kits do is reduce the gear overlap period. This reduces band and clutch friction and lowers tranny operating temperatures in situations where the tranny is shifting a lot.
None of these things apply to my situation. I don't tow much at all, I let my truck warm up in neutral in the morning, and when on the trails, I stick to one gear, seldom shifting around.
Shop suggested I drop my valve body and remove the valve body check valve for the forward clutch pack. That check valve partially blocks the fluid flow to the forward clutch, giving you slower, softer engagement. Removing that ball will speed my forward engagement and should eliminate my problem.
He also suggested I get another tranny cooler. I have one, I will be adding a second in series.
What do you think?
