Erratic shift in tranny for my E250

Anyone have advice for my van's transmission woes. I have a 1997 E250 with 200,000mi that shifts all over the place when cold and starting from a stop. Once it's warm or exceeding 30MPH it smoothes out.

I had the tranny rebuilt at 170,000mi but they did not replace the solinoid pack at that time. Two weeks ago this shifting thing started and they tried replacing the TPS first and then the solinoid pack, but neither worked.

Any help would be appreciated.

Mark

status update please...

Mark, my 2000 E250 A4OD w/>155k miles has same symptoms you describe. Also, gives hard shift when at highway speeds, and I hit the gas for passing. How did your issue get resolved. Thanks.

Turns out it was the valve body, which also wasn't replaced in the original tranny overhaul. Got disgusted with the tran shop and went to another one, they fixed it and it runs great.

Thanks for the info. What does having a valve body replaced cost where you are?

Fresh Mobil 1 Mercon V

After much crawling under van, staring at hoses (rookie), took E250 to local Jiffy Lube, who used T-Tech device to swap out ATF Mobil 1 Mercon V 14 Qts I provided. "Informal fee: $40". Seems to have helped, will know more when I complete 1500 mile trek in 2 weeks.
JiffyLube varies shop to shop, as to whether they will even use provided fluids, and there is no 'warranty' since it's not their fluid. Price quote $119 at one, $109 at another, and they seemed to not understand at another.
I observed the entire process, and lacking Spanish skills was a problem for me, but after them wasting 14 Quarts of Jiffy ATF, I found a manager to help get it done. I know which hoses were used now, still not sure which is 'return', and I can figure that out later I think.
End of day, the Manager settled with me, $40 cash, instead of quoted 109.
Interesting, eh?

Thumbs up

Those tranny flushes are a crap shoot. First they do not get all the fluid out. Also they do not change the tranny filter. On my 94 E-250 ,351 and my 95 E-150 ,302, with over drive trannys . I did the trans fluid and drained the torque converter, which the shops do not do with flush ,along with not doing the filter. ($30) A complete filter, gasket, fluid cost about $60-$65 and a little patience and work, but not that hard. On my 250 it was shifting all over the place and also shifting hard. Did change and also disconneted the battery to erase the memory and then took cruise to reset it, and good as gold. Tranny guys (2) said it needed new tranny, only had 74 K on it. Glad I did not listen to them. Once I did the 250, I decided to do the 150 with 133K for good measure. The flush just drains what it can, and not all of the fluid. Also you can see what is in the pan when you drop it. Glued magnets in both pans to collect any metal pieces in the future.

kevin-11,
Thanks for the info. e250 running well today, my son informs me from SyracuseNY (actually Baldwinsville) where he is Trophy Carp fishing this week (noted you like to fish). My main interest was to see any performance difference. I tried to get a shop to drop the pan/change gasket and filter, and drain the torque converter, and they said no. They quoted pan drop/filter/refill at $160, and I told them forget it, planning self change. I am not a mechanical person, have no torque wrenches or deep metric sockets, etc., and got confused with the various hoses, so I abandoned that plan, had Jiffy Lube do the fluid swap for me while I watched. They pumped a bunch of their own fluid, by accident, then I found a manager who spoke spanish to get the 14 quarts of Mobil 1 MerconV fluid pushed through the system, so my guess is most of the old fluid (no filter) was displaced in the process. I plan to have another local shop drop the pan, change the filter, and top the system off in the near future.
The morning slugishness (cold engine), and the 'passing' hard shift seem to be gone at this point. Will know better after the drive from Syracure to Boston, then back to DC next week.
Tight lines!

Hey John, The pan drop does not rquire any real special tools. Just take out most of the bolts and leave the 4 corner ones. Then drop them one at a time so the pan comes off at an angle so you know where to place the bucket to catch the fluid. Then disconnect coil wire and tap ignition while buddy keeps an eye out for the drain plug in the converter. I too was told $160 for the change, about right. You just have to make sure they drain the Torque converter and change the filter. The filter is not hard to change either, just 2 bolts through the center. Really do not need a torque wrench to do the job, just do not over tighten the bolts. I must admit I had a friend help me since I am in a wheelchair, but even so the job is not that dificult just a little messy. And since I believe in saving money ,I would rather do it myself and spend the extra on a BBQ afterwards. The right fluid is essential! Good Luck.Yes I love to fish, salt water here on Long Island, Flounder and Stripers are running now. Good Luck, Kevin
