i have a 2009 hhr panel i bought brand new feb 2010 just hit 63000 i had my trany service done this is the first service i had them use synthetic fluid as i only use synthetic moblil oil and change every 4000 to 5000 i dont go by the oil life idicator how offter should i do my trany service useing sythetic fluid i drive mostly hwy miles

 

Well,
A) if you don't go by the Mfg recommendations for the engine oil, why do you ask?
B)I believe the standard transmission fluid is Syn, maybe wrong.
C) Why not just read and heed the Mfg recommendations in the freely available manual? If it is not in your glove box, then it is on this site somewhere or at the dealership or the Chevy website.

Anyway, my point is that since you point out in your post that you do not believe the oil monitor, and you don't believe the trans service recommendations (never in normal service). Why then agonize over making up your own schedule?

I don't mean to sound harsh, I've just had a bad day.:s tirthepot:

 

Automatic and Non SS Manual Transmissions use DEXRON-VI Automatic Transmission Fluid.

SS uses Manual Transmission Fluid (GM Part No. U.S. 88862472, in Canada 88862473). I believe this has an additive that makes is semi-synthetic.

 

I have an '06 HHR with 126,000 miles. I have treated my car very well knowing that if I took care of it it would take care of me. I have done my tune ups with Chevy, I never asked about the transmission because it was always in tip top shape. When I went to Jiffy Lube to get a high mileage synthetic oil change, I asked him to check my tran fluid level I felt it was low. The guy actually laughed at me and said those cars don't need tranny fluid. After driving it today in 100* heat I'm concerned I am actually seeing my first signs of car trouble. Is it safe to add fluid and pray all is well or do I make a trip to Chevy first thing in the am?

 

Welcome!! I wondered about the quoted post as far as 100000 miles winning the award for the most miles until I saw that it was from 2008....anyway, on what do you base the thought that the fluid level is low? Have you noticed any signs of leaking? The Jiffy Lube clown isn't quite right. They do need fluid; it's just that they are 'sealed' and can't be serviced in the 'normal' way in that you can't just 'top it off'. At 126K, even in normal (not severe) use, it's time to have that fluid and fliter changed (IMO). Transmission shop like AAMCO could do the for you and would cost less than the dealership.

 

Sorry, couldn't see the date on this post, but I'm the second owner of a 2006 HHR and I have 140K with verry littte corrective maintenance. ( mostly done myself with the help of this site!!!)

 

Commendable, but I think you've missed the point; both that of the thread itself and of the particular quoted post.....
