Hey, E4OD guys........

[BDAB]

we are having problems with a 1995 Fleetwood Class C on a '95 E350 frame. 460 and E4OD. My transmission guy put a switch on it to lock up the torque converter in any gear at any speed (brake pedal disables it, default position on start up is off, it does not get used). I have installed a switch that reverses the logic on the OD so it's default setting is off when you turn the ignition on, she knows about this and only engages the OD above 50 mph.

I had the Transmission flushed and the filter changed august of 2008, it has been driven approx 6000 miles since. it has 60,XXX miles on it. Last time I drove it it shifted strong ...... I-40 in AZ holding 80 mph on the grades .....

My mom called me yesturday and told me the transmission was slipping, my mom is often wrong about these things so I ask her a bunch of questions and it turns out that it is not slipping but rather it is not shifting. It holds 1st gear for forever and a day and then gives her whiplash when is shifts into second. wont shift into 3rd until 45 mph ... and then other times it works fine like it always has. I had her BF check the fluid anyways and he said it is full and a good pinkish reddish color, does not smell like burned wood chips.... and no gritty feel to it.

She recently had to drive threw a wash that was a little rough and this is when it started acting up.

is it possible that she ripped some wires loose and it periodically goes into limp mode?

I have also read that a worn out ignition switch cause a similar problem in the 4L80E ........ could it cause this problem with an E4OD? I ask this because she is indeed been having problems with the ignition switch and this vehicle used to sit around a lot, you have to fiddle with it to get it to stop chiming after you turn it off and take out the key, some times it stays on even though you can feel it click when you turn the key to the off position ...... going to have her change it anyways but we were hoping it would hold till my next visit in April......

On the old IDI diesels, the same issues could result from the throttle position sensor being out of wack. I definitely agree that it is an electrical issue because it is intermittent. Also look at the shifter position switch. if that is out of adjustment, it can cause issues.

I told her to get the ignition switch changed (because is needs a new one anyways) and go from there. I also told her to get it done at the ford dealership in Blythe because I don't trust anybody in Quartzsite to do it......

Any progress on this?

[BDAB]

don't know yet, she hasn't called to say she has got the ignition switch changed.

sent her to Blythe to get the switch changed, paid for it over the phone. Cost $75 forr a new switch and tumbler installed. The transmission problems went away.
