i have an auto trans (i got a good deal on the car) and it seems to really be jerking when it shifts i know it could be a few things but has there been any problems with the trannys in the 2000 model? any help would be appreciated

 

the tranny you are refering to is the 4R70W automatic, it comes in all 4.6 powered trucks, and all mustangs that have the automatic option from 96-04. I dont think their were any differences in the years, i would change the fluid to good high qaulity stuff along with a new filter and go from their.

 

jerking as in like shuddering? is it all the time or only at WOT?

has the fluid ever been changed?

 

try disconnecting the battery for 30 mins or somethin like that

to the best of my knowledge its never been changed. so thats something im gonna do this weekend. and its more of a jerking, just when it shifts. crusing is fine.

 

im JW why would i disconnect the battery? isnt it the transmission most likely the problem?

 

All automatic transmissions are now electronically controlled, unlike the old, mechanically controlled ones. This means a computer tells the transmission when to shift and how hard, as opposed to hydralic valves. Disconnecting the battery might fix your problem if its a computer shifting problem, since it will go back to default settings.

P.S. How are you doing with finding the empty slot for the radio? I noticed the Cobra R has 2 empty slots- maybe a Cobra R replica site will have them, if Ford doesnt work out.
