4r70w vs 4r75e???

[95.0mark]

So the 75e is tougher? correct? but id assume the 70w is cheaper and easier to rebuild? both same smoothness?

[Chrm97PI]

same transmission, 4r75e has a stronger input shaft i believe

Wrong.

can you explain then good sir

Neither your yota or your hyundai have enough torque to break either, so why does it matter?

W is wide ratio, E is electronic controls. 70 vs 75 is the torque rating (x10) of the input shaft. They do have the same gear ratios however, the W was to differentiate its ratios from the 4R55E and 4R44E. I don't believe the W has electronic controls though. There are 4R70E and 4R75W models out there too...

The W is only meant to describe wide ratio. It has nothing in common with the A4LD series of transmissions, or to tell them apart.
The 4R75W has a different stator support, improved converter, the planetary gearset has a newly designed manufacturing process, sun shell and forward sun gear is different, the pump body has a new piston design, planetary ring gear has a OSS lugs, among other minor details.

In newton*meters!

4r70 will hold up plenty of power as long as its built right. Lentech has one rated to over 1000hp.
