Re: Beefing up the BTR 4speed
Thanks for that 9psi EB. Do you think that increasing the spring pressure on the line pressure relief valve is the way to go for increasing line pressure in the whole tranny. I know this sounds obvious but may cause other problems. I see that the S5 resistor mod would be beneficial for saving the clutchs by changing quicker. I'm reading a Ellery publication "Ford Transmission Repair 1960 to 2001". In the BTR 4sp section,it states "
#2 clutch piston is prone to cracking around the centre bore, this will cause pressure to be applied to C4 clutch at the same time and burn out clutches". Does anyone know whether this was the problem with the early EA 4sp that was subsequently rectified or whether this is a possible problem on all of them. The book is not clear on this.
