Trans shield rule??

MEXJOE · 01-09-2018, 03:11 PM

I am looking for some clarification on the new TRANS SHIELD rule.
What is required for a trans shield / blanket?
Will an ultra bell be good, or do you need more?

Ed Wright · 01-09-2018, 03:54 PM

I was not aware they changed it this year. Glad I saw this while mine is out of the car.

From what I understand when you're in Stock Eliminator and running quicker than 10.99, you must now either have a SFI-approved trans case (ATI, Reid or JW case), a SFI-approved shield or a SFI-approved blanket. An SFI-approved bell housing isn't required on any Stock Eliminator automatics unless you're quicker than 9.99 from what I recall.

Is that 10.99 based on the Index?

No, I understand the 10.99 is based on what you actually run. If one car ran 10:98 he would need it and if an identical car ran 11.01 he would not need it. I would hope I am wrong on this but it is what I have been told.

So, nothing for SS? I have a TCI shield on mine. Where did you guys see the new rule changes?

I think this is still waiting to be finale
Don't feed into it all...

Here's the wording for stock...

"any car running quicker than 10.99 must be equipped with a transmission shield meeting SFI Spec 4.1. Any car running quicker than 9.99, SFI 29.1 automatic transmission flexplate and SFI 30.1 flexplate shield mandatory. See General Regulations 2:12, 2:14."

General reg 2:14 doesn't provide any further clarity but if running a car that goes 10.99 or quicker then I sure wouldn't show up without a blanket or shield. May very well be one of the "easy tech" items they can check easily in the lanes, kinda like tethers; they just have to bend down further.

Stock rule is here:

Any car running quicker than 10.99 must be equipped with a transmission shield meeting SFI Spec 4.1. Any car running quicker then 9.99, SFI 29.1 automatic transmission flexplate and SFI 30.1 flexplate shield mandatory.

As already posted, the Ultra Bell alone is not a transmission shield, but will serve as the flexplate shield if you need one.

Super Stock rule appears to be the same as last year. It is basically the same as the Stock rule, but there are also class-based requirements in addition to ET-based:

Cars in SS/AH through SS/MA, FSS/A through FSS/M, and any car running quicker than 10.99 must be equipped with a transmission shield meeting SFI Spec 4.1. Cars in SS/AH through SS/JA and FSS/A through FSS/M, SFI 29.1 automatic transmission flexplate and SFI 30.1 flexplate shield mandatory. Aftermarket automatic transmission bellhousing permitted; must be labeled as meeting SFI Spec 30.1 for automatic transmission flexplate shields and must be NHRA-accepted. Aftermarket OEM-style replica case, NHRA-accepted, permitted. See General Regulations 2:14.

Cars in GT/AA through GT/LA, FGT/A through FGT/J, and any car running quicker than 10.99 must be equipped with a transmission shield meeting SFI Spec 4.1. Cars in GT/AA through GT/GA and FGT/A through FGT/J, SFI 29.1 automatic transmission flexplate and SFI 30.1 flexplate shield mandatory.

What difference does it make on your e.t. If a transmission blows up I think you would
want the protection.
