Please Help...

I have a 93 AWD Aerostar extended minivan that has about 155,000 on it. The Trans was rebuilt at around 30,000 from Ford on a warranty from the previous owner.

Getting to my problem, recently I have noticed that only in third gear I get the jerking (feels like jerking from being in the wrong gear while driving a manual) when I step on the gas to pass or climbing hills etc. First and second do not have this phenomenon while in drive or manually shifting with the lever. I have noticed the occasional clunk when I take my foot off the gas and then depress again but this doesn't happen very often.

I have checked the fluid, levels are ok but the fluid smells a tad burnt. I have read that it's not a great idea to change fluid on a tranny that has high mileage especially if they haven't been routinely maintained. My final question is should I change the fluid/filter and if so will it do anything.

This last month has been a very interesting one, new plugs, new muffler, new brakes all the way around, new shocks all the way around, and a new starter.fun fun fun!!! I can't begin to imagine how much I would paid if I didn't do the work myself. Boy are minivans fun to work on!

Any help or info would be greatly appreciated!!!

This van has an overdrive tranny, right? Have you tried taking it out of OD to see if the problem persists? Sounds like the lock-up convertor may be getting old, or you are having some problem with it.

Yep it sure has overdrive and if I shift into it I am having the same symptoms. You say it could be the "lock up converter", would this be something a novice mechanic could replace or would you suggest a certified mechanic look into it. Also you have any clue how much a new/used converter would run me?

Thanks so much for the help!

The convertor is the torque convertor. It uses an electronic module to lock it up at a certain speed/rpm. If the convertor or the module are going bad it can cause the symtoms you mention. I wouldn't suggest a novice attempt this repair. You should take it to a tranny shop and have them diagnose it. I don't know the cost of a new convertor for your van, but I guess it would be around $300-$400 plus labor.

mine does the same thing! but i just take it as normal. I mean, its done it since i got it, and its been about 2 years. mines a 91 3.0 2wd with 167,000 miles. someone told me to check the U-joints. maybe theres slack in em' but i never got around to looking. but I hear a clang when its put into gear.

check the U-joints on the driveshaft.

wanna get AWESOME mileage?? I get 31 mpg @ 70 mph flat ground freeway.

I put a K&N cone filter right onto the throttle body, and got rid of the filter box and stock rubber tube. it's mounted directly onto the throttlebody opening.

then i took out my Cat. converters (legal here in oregon) and put in dual 2 inch exhaust. its way too loud, but gets great mileage and hella power now. I am going to switch back to single pipe and performance muffler to quiet it back down.
