VSS reluctor tooth count

VSS reluctor tooth count
In a previous format, one of my T56s was an LTx variant and I had to make make and install a custom 40 tooth VSS reluctor wheel..... Fast forward to present and I'm mostly done converting the T56 to an LSx variant; already set mainshaft and countershaft endplay & preload, just need to set Countershaft Extension endplay.....
I'm wondering if I can reuse this 40 tooth VSS reluctor and change that parameter in the tune when the time comes or do I need to find another 17 tooth VSS reluctor???

Okay, thanks for confirming that. I don't think I've ever seen or heard of a TBSS with a 6 speed swap. Got any info or pics on that? My swap is a 90 RCSB Silverado. Truck was originally a 210 HP TBI 350 with a 700R4. I built a mild TBI 350 for it that probably made ~300 FWHP and drove it around like that for a while, torched the 3/4 clutch pack in the auto, tore it apart and fixed it before finally putting a T56 behind the mildly modified 350......
The 350 finally wore out so I've got a LQ4 sitting in there now, should be ~425 FWHP with a cam and headers, maybe more if I can score some 243/799 heads. Rearend is a 14bsf with 4.88s and TruTrac, and I'm just now finishing up the disc brake conversion on the rearend with NBS discs.
What gears are you running with your setup and how do you like them? I find the 4.88s to be perfect for me. It would really move in 1st through 4th with the old 350, hoping this LQ4 will really make it quick. 6th gear @ 70mph with my 29" tires is right under 2000 RPM, even with the 4.88s.

To my knowledge, I'm the only one that has done the swap to a tbss. There is a link in my sig to a build thread I posted here. I kept the stock 4.10s in it. The gearing in the tr6060 was pretty much perfect.

That's really cool. How does the fluid cooler work on that one? Is there a pump or what?
How do you like the shifter? I have a Pro 5.0 that used to be great but it's pretty worn out, thinking about an MGW when the time comes.

Please help! I have a T56 trans from Silversport (SST) transmission and a 411 PCM from PSI industries. The T56 has a 17 tooth reluctor. SST sells a module that plugs into the Trans VSS output and then provides a reverse lockout for the trans plus a converted VSS signal (40 count/rev) to the speedo > cruise control. The price is almost 300.00 plus shipping. PSI can retune my PCM for the 17 count reluctor, however their stand-alone wiring harness does not include wiring for the reverse lockout from PCM to trans. If I modify the wiring harness or PCM for these features I void any warranty from them. What's my best course of action? I do want reverse lockout, I do want cruise control and I am going to be using Dakota Digital instruments.

What are you trying to do here exactly? Save some money? I get that. But sometimes, it's better to buy once cry once.
If it's just a simple lockout function you're mainly concerned with, I think you could set that up on a simple toggle switch.
