Drain Plug
$9.34 list
$5.84 your price

Lower Deflector
$86.23 list
$69.59 your price

$362.81 list
$258.51 your price

EDIT: looks like the TCM is on backorder (that's the bad news)
I can still get you one (located from another dealer) but it might take a couple weeks
while looking into this I checked the original part number and found out that there was stock at VPI (vintage parts inc)
the discontinued original modules are cheaper from VPI (usually VPI keeps the same pricing even though they pay pennies on the dollar for discontinued stock)
if you want to go with the old/original part number (#24223207) from VPI it will only cost you $170.72 and it will only take 3-4 days for me to get it

shipping on the drain plug is going to bring you above the list price... you might as well just go to your local dealer ... but if you insist i'll sell it to ya

i would waste more gas going to my local dealer and please they suck at customer service and everything else, including there parts department...

06-08-11, 09:41 AM
shipping would be $13

so your total would be $18.84

Chris...i got the plug in the mail thrusday, but just opened it today. this is not the oil drain plug, but it is the tranny plug. the oil drain plug is not a hex, but just a regular wrench fits on there...this is unless they changed them recently, because my 03 and the 06 that i always work on have the same plugs

06-19-11, 12:52 PM
the part number did change... so that might be it

unless i goofed...

what's the part number on the bag? there should be two stickers... make sure they both have the same part number on them
(and double check it against the part number on the invoice)

i'll double check that number against the parts catalog in the morning tomorrow when i get in to work

06-19-11, 07:19 PM
after looking at post # 2 in this thread and looking at the invoice and the part packaging itself, all the part numbers are the same. only problem is, on the parts packing it says trans plug, therein which i know for certain that it is the tranny plug and not the oil drain plug like i need. so can you price me the oil drain plug

06-20-11, 09:58 AM
after double-checking and asking a few of the guys in the shop and everyone seems to agree that the packaging is just incorrect in calling it an A/TRNS PLUG .. everyone says that is the oil drain plug



06-20-11, 01:11 PM
that is the exact plug and packaging i received from you...do you have any other kind of plug around there you can snap a pic of? because my 03's oil drain plug is not like that at all, neither is the 06 CTS that I work on either. even my 05 and 06 STS dont have that has an oil drain plug. but that is the same exact thing as my tranny drain plug though

06-20-11, 01:13 PM
i just dont want to drain the oil, then this plug dont fit right, then i need another one. i dont believe in recycling my oil, so i just dont want to pay for two more 5 quart containers of oil you know

06-20-11, 05:45 PM
the only way that plug won't work on your car is if it's been stripped before and someone put a oversize plug in there

that plug has been used on this engine back when it was the 3.0L in the catera and the saturns ... the '03 CTS 3.2L was the last year of this engine (in cadillacs... saturns used the 3.0L thru 2005)

i can't really think of any other reason that your plug isn't the OEM plug (as far as I know they haven't changed the design - it's always been torx)

06-20-11, 10:41 PM
well i have a difference of opinion here...i asked the question in the 1st gen CTS section and the concesus is that it is a 13mm hex head and not a torx head...


06-21-11, 01:21 AM
well i can call GM's parts help line tomorrow and tripple check with them
they'll have a record of issues tied to that part number and we'll see what they say

06-21-11, 05:08 AM
if you wouldnt mind...it just doesnt seem right to me that all other CTS's including mine have the hex and only one other person had the torx. but if torx is what fits, then i will use it and be happy, i just want to be 100% on it before i purchase more oil to do this change...sorry for all of this extra stuff bro

06-21-11, 08:50 AM
gotcha covered... i'm calling them right now

06-21-11, 08:59 AM
there have been other people to call asking if there has been a design change to this drain plug

they said there were about 3-4 calls in the last 6 months asking about this part number

the drain plug is also used as a trans drain plug (so that's why the packaging says A/TRANS DRN PLUG)

the agent I was talking to said that he was very confident that you should be fine based on those 3-4 instances of people calling in with a similar concern

it's quite possible that some cars got different plugs at the factory or that some oil change places toss out the factory plug

the only way i can see this going bad for you is if your plug was stripped and was replaced with an oversize plug
(but it sounds like other people have the same plug as you so it was probably just switched out for convenience)

06-21-11, 11:44 AM
okay no worries then, i will go with it and hope for the best. thanks for completely verifying this and understanding my concern of what my car has and what i have always known of my car to have

06-21-11, 12:05 PM
i totally understand... let me know if you hit a problem, but i think you'll be fine :thumbsup:

06-21-11, 01:17 PM
okay will do...
