Because I have a shudder problem in my 1993 f150 xlt, with e4od. (87,000 MI). I'm thinking of changing the transmission fluid. I wanted to do this because I have tird everything else I can think of.
But what I want to know is with this amount of miles, should I change the fluid old school or have it flushed completely?
I have heard of the problems a flush could cause.
I bought this truck 3 weeks ago and I don't know if the previous owner ever did one, but the fluid is still pretty red.
Shudder happens at top of 3rd gear and in OD when I level off pedal. But it's not always consistent. Sometimes it runs fine.

1993 F150
engine: 302
Trans: E4OD
Mileage: 87,000

Truck sat for about 6 months before sold, previous owner passed away.

Thanks foks!!

When you say shudder? do you mean like the engine makes like a pinging or rattleing noise?

 

no, it shakes after leveling off pedal in OD and then accelerating.
Its not totally consitent though. Yesaterday it didn't do it when I took it to the dealer i bought it from. (of course)
But it does chatter slightly, which i am a little concerned with also.

Thanks for the reply.

 

I was having the same problem. I drained the torque converter and the pan. My 4R100 uses Mercon, so I replaced the fluid w/Mobil 1 synthetic. Problem solved, no more shudder.

How long will the Mobil1 last?
