i have a 95 5.0 and i was told that my torque converter is locking up and causing a vibration in the rear as it is shifting. i have a stock automatic trans with a shift kit. any ideas?

[95wip]

you probly just suck!

[stang94]

how bad can it be if your suck at automatic?

[Racinjason81]

it could be possible if it causes the engine to lug.also check your driveshaft
for any weights that fell off

Might just be time for a new converter...With that shift kit, you should be running a trans cooler too...Nice cheap mod to help with the trans...

This transmission shuddering is known problems:


This internet thing is wonderfull
Try some googling and you will find almost anything :-D

The shudder during 3-4 lockup is a breakdown of the oil-friction interface at the clutch in the converter.
This breakdown is caused by oil type, temperature (put on a cooler), and energy (or calibration).
This breakdown causes the shudder.

For the sake of your car you should get the cooler, mercon V and new calibration that is recommended in the TSB.
With all 3 of these, you will most likely not get shudder again.

Reverse shudder is an alignment problem with the gear set.
The gear set is aligned on 3 bushings.
These 3 will "fight" each other causing a light throttle shudder.
This doesn't hurt anything, and usually goes away with miles.

The older torque converters (trans's built before 10/94) or Mark 8's and
Mustangs up to '97, are a less "optimal" design.
The converters built after this point are good.
The difference is the stiffness of the lock up plate and the radius of the friction material.


Tips:
Anyone who owns a AOD, AODE or 4R70W transmission it is very important that you replace your 1-2 accumulator ASAP!
They like to go bad. It was part of a TBS and thus not required by Ford to recall all AOD and AODE transmissions.

Reason: Aluminum style wears out the case and burns up the 2nd clutch. 1-2 accumulator piston changed from aluminum
to molded rubber. (Updated molded rubber style) F7AZ-7F251-AA. (See picture)

Recommendation: Always update to the rubber accumulator. If the bore is worn in your case you can salvage it by
Scothbriting the bore real good and installing the rubber piston.
Only after 40K on my transmission visable signs of wear showed on the aluminum acvisibleor and bore it fits into.
If not replaced a rebuild or worse a new case would have been necessary. You do not have to remove the valve body
to access the 1-2 accumulator. After you remove the transmission pan the accumulator is held in place via a snap
ring in the drivers side upper corner of the case.

thanks for the good info, i appreciate it

[95stangvert]

i ended up using a trans additive that fixed whatever was happening
