4 speed autos EA to ED

hi all, does anyone know if there were any internal differences between the BTR 4 speed in the series II EA up until the late ED?

Did Ford or BTR strenghen them at all as they were slightly unreliable in EA??

Any comments would b great...... taa

Hmmm, im not sure about the internal gear ratio's but I know for a fact that the ED's had different stall specs on the converters than the EA had. EA was something like 1850rpm and ED had 2200rpm... anyone confirm this?

Found some stuff on the BTR's...

Gear ratio's were the same across the 85/91/95 boxes.
Stall speeds on the converters were 1950rpm(85LE), 2200(91LE), 2400(95LE). The only other differences i can find are that the boxes had slightly different line pressures..

Cheers

So does that mean the auto behind the 5.0L in my EBII has a 2200 RPM stall converter.

Internally, the 95LE is a stronger box. The mechanic that rebuilt my box did go through the differences, but I can't remember the details. It was to do with the clutch setups and the bearings used.
