Here’s another newby with a fresh 200-4R rebuild with some weird things happening on first start and pressure checks. I rebuilt it myself with mostly new billet parts, I also have the tci manual VB (that requires both accumulator pistons and springs to be removed. The pump got the CK high pressure kit .555 TV .300 reverse boost. The car isn’t on the ground yet so all this is on jack stands with the rear tires removed
Here are the pressures at 700 rpm (made a mistake thought idle was good, I see now 1000 rpm is standard, and tci published values are for 2000)
Park-170-190(high? Maybe still too cool?)
R-150-170
N-140-160
1-120-130
2-110-120
3-110-120
4-110-120
It starts high and as you move through the gears pressure drops. If I rev the engine in gear pressure rises to approx 200 psi.
There’s no reverse, the pressure gauge twitches and pressure changes but the hubs won’t rotate even when I rev it. Hoping it’s something simple.
Second issue is a bind on the 2-3 shift, the hubs stop so I’m assuming it’s a bind. In the CK manual Chris talks about enlarging the #5 3rd accumulator orifice in the separator plate. The TCI VB has its own separator plate and that area of the plate is solid; no holes.
Since I’m double feeding 3rd I think need to drill an orifice in the tci separator plate at this location but not sure.
I ran out of time working on it today so I’ll try again tomorrow and compare pressures for the tci system at 2k rpm, but the reverse and bind are likely not going to be solved by that. Any ideas? Thanks in advance!
