Do you mean E4OD? The shift points vary by engine. The maximum RPM for a shift will be lower on a diesel than a gas engine, for example.

It's the engine that limits that. If the tranny can handle 11,000 but the engine is good till 8,000 then you get to pick up pieces on the road. My thinking any way

I know on my 95 E350 with the 460 engine, the E4OD will shift at ~4800rpm at WOT. The 92 F150 with a 302 shifted around ~5200 at WOT I recall.

I haven't driven a I6 300 yet(soon to replaced the AOD with E4OD in my 89 F250) so my estimate would be around 4000 to 4800 RPM at WOT. The big I6 300 engine looses all power after 3800 rpm and winging that engine too high is not good!

Okay good to know, my F-150 351w has been sitting for 4 years just about get it back on the road with a new motor and all but I know it Max shifted at 3800ish to 4000 and I didn't know safely spin it to 5 grand guaranteed putting 400 horse on a virtually stock rebuilt transmission and then abusing it isn't the best idea but definitely a lot more of a Power Band being needed there

and that's my thought exactly just in reverse I know my motor will probably run the 5500-6000 if needed peek power still being 4800-5400. . . but if the tranny stock only handled 5000rpm safely before risking it going *kaboom* it's just something I want to know find out, and I truly don't know Transmissions yet I can build a motor but Transmissions are another language to me still so I might as well ask
