1997 E-150 30-45 mph vibrations
I have a problem with my 1997 E-150 4.6, 100k miles. Under moderate accelartion between 30-45 there are vibrations, if I step on the gas a bit harger the vibs go away. The vibs are only there on slight acceleration (or even sometimes when just running at steady speed 30-45) when in 3rd or OD between 30-45 mph. Any thoughts ???

I have the same van and the same problem. I was thinking it could be the EGR valve and will try disconecting it to see. I'll let you know in a few days.
My son works in an auto repair shop and the mechanic says it's a common problem for a 97 and it's probably the torque converter. He said I should have it "COMPLETLY FLUSHED". Not just the routine filter replacement and refill.

Trans Problem
It's not the EGR valve. Took the "dog house" cover off and disconnected the EGR valve. Drove a few blocks and with the cover off I could hear and feel something in the trans. Sure hope it's as easy as a flush or were looking at some major bucks. Not sure what I'm going to do. If you get the flush, please let me know. Whatever it is, it aint good!

Had the Trans cleaned/flushed by Ford. $160.00, Aamco wanted $99 but I didn't want to chance it. The problem got better after 100 miles of driving. I belive it may be cured. Had 60,000 miles on it. Ford said it shouldf have been done at 30,000.
Good Luck

That is in fact a torque converter clutch shudder. This is quite common on fords with the 4r70w transmission. Servicing it regularly will prevent the problem (every 30K miles at least) from happening.
What happens is the additives in the fluid that dampen clutch engagement dissapate with age. A fluid change will solve the problem. Its also a good idea to add a bottle of Lubeguard.

Its a transmission additive. Unlike the "miracle in a bottle" crap, Lubeguard is actually good stuff. You can get it at better autoparts stores or most transmission shops. Its probably the only additive that a reputable transmission shop would use or sell.

Change the fluid and add the Lubeguard.
More info at: http://www.lubegard.com/automotive/trans_atf.html
"Lubegard Red" as its called in the trade is the standard of the transmission industry. Most any transmission shop knows about it and uses it. Its not well known in the retail automotive products industry and it isn't common. You may be able to find it in Autozone stores packaged as "AAMCO Transmission Additive". Its the exact same stuff.

i had the same problem,
it is TC Lock up shudder.
the Repair is to replace the TC with a NEW Torque Converter that will not slip while trying to Lock Up.
Do NOT add anything to your Tranny fluid,
JUST Replace it with new ATF.
mine has 130K miles on it before it started vibrating, TC Shudder.
I just got the Whole tranny rebuilt, ( shifts MUCH FASTER now ),
and a New TC.
repeat...
just change ATF with new Fresh Fluid. No additives!!!!!!!
if they were that good, the manufacturer would put them in there in the first place!!!!!!!

The shudder is in fact the Torque Converter. But the shudder is caused by the loss of the additives in the fluid that dissapate over time. The additive package cushions the converter clutch engagement and prevents the shudder. In most cases, changing the fluid will solve the problem. There are some cases where the converter clutch gets scorched or burned and changing the fluid will not solve the problem.
As for additives, most are junk, but Lubegard _IS_ what the manufacturer puts in the fluid. Its a very concentrated dose of the same additive package than the manufacturer puts in when they make the fluid. This is well known in the transmission rebuild industry but virtually unknowns outside it.
If a fluid change and a bottle of lubegard doesn't fix it, then you will have to replace the TC.

a lot of tranny fluids say right on the label that they prevent shudder. usually you feel it around 35-40 mph when the trans is going into overdrive. you can check this out by hitting the overdrive button on your shift lever while standing still, then accellerating with light pressure up to about 55. replacing the fluid with a good quality fluid should eliminate the problem.

Had a flush and used additive - problem solved
I had the same "shutter" problem about two years ago, at about 130,000, our our E150. If felt like you were going over a washboard at certain spees. My shop flushed the tranny and put the additive in (not sure, but imagine it was the same one discussed - Lubeguard). He said this is a common problem an in about 80 - 90% of the cases, the flush and additive will cure it. It sure took care of our problem and at 154,000, we have had not further problems. Spending $120 or so compared to a new tranny was quite the welcome relief.
