1993 f150 I think the trans shutters between 1500-2000 rpm does it in drive and OD I think may be lock up converter. E4OD trans. Any ideas. thanks for any info
I took rear drive shaft off and drove it still did it. Put brake on hit gas did brake stand didn't do it.truck vibrates dash, stearing when doing it .doesnt miss motor runs great .only when going down road doesn't do it in 2nd gear

 

It's tough to grasp exactly what someone is trying to tell you when different words mean different things.
My first question is could this shutter be an engine problem?
Why do you feel it is coming from the trans?
Is it speed related?
If you get the engine up to the problem RPM in park, or in gear with the brakes on ,can you create the shutter?

 

E4OD was prone to torque converter shudder. Depending on miles, type use and prior services, sometimes a fluid change will help, some additives too.
Do a net search for 'E4OD shudder' and see if it follows your complaint. Without driving the truck, hard to say if it's engine related, Minor/ moderat shudder, or time for a new converter. Also, would depend on how many miles on the current trans for a partial repair. Trans fluid condition? Burnt?, dark? Or nice red? All to concidered if trans shudder..
