4R70/4R75 BCA Separator Plate
I used this separator plate for 4 years. It is a BC Automotive (BCA) separator plate, which is somewhat similar to performing the J-Mod on your existing separator plate. This plate will fit 4R70E/W and 4R75E/W transmissions. However, it does not have the holes drilled for the third reinforcement plate, since it was originally designed for a 2001+ transmission that only has two reinforcement plates.
I have used this separator plate WITH and WITH-OUT the lower 1-2 and lower 2-3 accumulator springs.
Your transmission will shift quicker and firmer with just the plate alone, but when you remove the springs, it shifts much firmer - my car was able to chirp the tires on occasion with this plate and no lower springs installed.
I am asking $75.00 shipped
for this separator plate. There is a slight dimple where the 2-3 accumulator cap sits, but nothing significant, and definitely no cracks!
I also have a used, original Ford main pressure regulator valve in very good condition that I will sell for an additional $10.00
Please call me at 219-614-0771 for more information. Thank you.
