Would like some help ,I have a 03 auto,trans is shuddering possible time to upgrade converter and valve body OR trade up to a 05 is the new trans better will I have the same problems or just change over to the stick and is that new CTD worth $$ to change, confused: confused: who 's got some feed back. come on you 2005 guys need to know the delli o

I should still be able to transfer over all my goodies

 

im guessing u have the 03 with the 47re? cause the 05 has the same 48re auto as some 03 and the rest of the 04 and o5 trucks... the 48re is seeming to hold up pretty well though

 

When does it shudder?
Going into lockup?
Starting from a stop sign?
anytime you step on it hard?

When was the last time you had it serviced?

Need to know more details.

 

bluebull,
The transmission will shudder around 80 km to about 110 km under mild to hard acceleration there never seems to be a problem below that. Both driveshafts have been redone at the dealer new joints along with the hanger as far as the trans goes the day I brought It home the trans temp light came on Dealer replaced recalled valve or something & about 8 months ago the I lost drive and reverse all together. Please Help

Thanks Don
