i know you are FI but are you turbo or sc? what WTQ are you making? Do you know what your trans temps where when it started slipping? How many miles / track days did you have with the clutch pack before slipping? Last edited by 86TOYO2k17; 10-24-2019 at 10:50 AM. |

So $500 for a used trans with less than 10k that will die again in a few years or SSP and hope TC and plates are ok? |

If I were you, I would probably go with a used trans. Much cheaper solution, especially if you have a garage and tools. |

Also would love to see a video of a an idle flash stall launch. Basically just mash the pedal from a full stop at idle. And brake stall if you can/want. Not concerned with actual acceleration numbers. Just how the VB and TC act when shifting and how the TC acts from a dig off idle. I’ve read a lot about how this all should work in theory, but being able to see specifically applied would be ideal. |

I installed the ssp stage 2 valve body with a full flush of redline (5 drain and fills) didn’t need to reset anything or do anything special just plug and play and ready to go.
Review Stock and even for the most part full bolt ons NA i would consider the trans pretty good. Quick and responsive. But once i went FI not so much. On my initial FI tune it would hit limiter/fuel cut in auto mode in 1st gear bcs it couldn’t shift quick enough, in manual mode i would have to shift 400rpm before I actually wanted to shift. My tuner was able to change some transmission settings/parameters to only have to manual shift 250rpm early and raising limiter to 7500 auto mode in 1st could now shift before limiter. I found myself only manually downshifting and letting it auto up shift for the quickest most consistent pulls. My trans also would sometimes slip on the 1-2 shift at WOT. Now with the stage 2 valve body it is unbelievable how fast and hard it shifts and grabs the gear. You don’t notice any stopping of or hesitation of acceleration in between shifts it is instantaneous. I can now upshift in manual mode again and it’ll shift only about 100rpm later but instantly letting go of the gear(clutches) and instantly firmly grabbing new gear(clutches) with no more “built in slip” for smoothness. auto mode almost short shifts its so fast.. My 1-2 shift hasn’t slipped at all either so far. This is an amazing mod for any AT owner who is FI it will add a lot of performance and actually should help extend the life of your transmission. You will really want/need a trans cooler though. The only down side is the shifts when casually driving are a bit rougher, the “built in slip” is bad for performance but good for smooth comfortable shifts. It is nothing I can’t live with daily driving, but if I frequently drove my wife/girlfriend in this car I would maybe not get it. Luckily we have the family suv for that. |

Thanks for the review. Are you thinking of getting the clutch upgrade from ssp as well?

Maybe someday, if the clutches start going out and need replacing I’ll use SSP clutches. Or maybe just swap valve body to a slightly used trans if the stock tranny holds up for a while. Clutch packs with install is expensive even if i pull trans myself, not something i could DIY like the valve body.

Thanks for the review. It's so hard to find detailed feedback on this topic. Do you have any videos that you could share of the stage 2 valve body upshifting the gears in manual mode under light load? Besides the wot shift delays, I really don't like the slop in the gears even while casual driving. It seems like the only time this transmission is programmed to return crisp, firm, DCT-like shifts is an aggressive, medium throttle take off from a stand still. Most other take offs or rolling start scenarios seem to result in slower, softer shifts with more slip (my car is a similar 86 with EdelbrockSC/e85/350rw). |

E85 edelbrock I would say you are a good candidate for the SSP VB. It takes out most of the slop under any load/throttle position. The best way I can describe it is say you make 60ft lbs at 10% throttle, on stock VB you shift gears and the trans disengages for .2seconds and then re-engages new gear but only initially applies 15ft lbs at .2sec, 30ft lbs at .25sec, 45ft lbs at .3sec and finally the full commanded 60ft lbs at .35sec. Very smooth transition but slow and sloppy. this effect can also be magnified the more power over stock you make. Now with the VB you make 60ft lbs, shift, disengages gear for .2 seconds and then re-engage new gear and immediately make the full commanded 60ftlbs at .2seconds, very quick and zero slop, but your getting hit with 60ft lbs all at once so it’s not as smooth. I didn’t really mind it much but it’s definitely noticeable. You do get used to it more as well. |

Thanks for taking the time to respond despite no longer having the car. It sounds like the SSP VB is next on the list then. I had read another review online and seen a failed install on YouTube where the reviewers said they could "kinda feel it" but that kind of review wasn't too helpful for me to decide to commit $1500 for the purchase price. Seeing how inexpensive used Autos are, I might just get a used trans from LKQ and just go through it all at once on the bench top.
FWIW, I also reached out to Bill at Delicious Tuning to see if its ever in his plan to offer something tune wise. I recall when I was down there he said something about wanting to be able to mod the Autos but am guessing this development may not be very high on the priority list. I'll reply here if there is any glimmer of hope there.... |
