#390 of 422 Re: 4L60E/4L65E trans info [taluhlabelle12] by kathy29 Oct 10, 2009 (7:22 am)
Replying to: taluhlabelle12 (Mar 26, 2009 11:33 am) Hi taluhlabelle12,   How many miles did you have on your 02 Chev Trailblazer when you had it at the dealer for your transmission or when GM agreed to pay for the repair? Also I cannot find the Internet link to the safety recall for the sun gear/sun shield, where is it? so many people talk about it but I have yet to find it on www-odi.nhtsa.dot.gov. If anyone reading this message knows where the Internet link is about the Sun Shell/Shield please reply with the link, thanks. BTW I have an 02 Trailblazer LT regular length with only 21K as of October 2009. I really can't afford to buy another vehile just to have peace of mind that sometime soon my 02 Chev TB transmission may bite the dust.

#392 of 422 2003 Chev. Transmission oil level to high by chainbreaker Oct 20, 2009 (6:38 pm)
I had a transmission problem, checked the oil level, to high. Drained off one quart, chacked the oil level, low. I had to put back one quart to bring up the oil level back to the normal full mark. Question why did the oil level rise, and why did it go back down. Replies to this message: burdawg (Oct 21, 2009 7:02 am)

Replying to: chainbreaker (Oct 20, 2009 6:38 pm) Was it warmed up and running when you checked it?

The truck runs good and then it starts sucking in air and the rpms. go high and the trucks moves slow can anyone tell if it is the transmission going out or can it be a sensor in the truck.

Replying to: trail03 (Oct 24, 2009 9:13 am) I had the same problem with my 02 tb, took it to a mechanic(good honest one, which not too many around this days) and he told me it was the engine fan pulley. Seems that a circiut goes out and that the computer communicates with the trans via that circuitry. The trans is not getting the info to shift properly coz of that circuitry problem. Got a new pulley from an authorized AC/Delco parts store for under 80 bucks. Installed it myself. When I started my tb after installation, I could notice immediately the difference in rpms and idling of the engine. Took for test and ran as good as new. Dealership wanted about 500 bucks for pulley with fan. Stated that pulley was not guaranteed if bought separately. This happened to me over 2 yrs ago. TB has been running great since. You can install without removing fan cover, but it will be tight. You can bend both fan and cover just enough to get pulley in there. Intalling screws will also be tight, but a bit of patience, you can get it done. Hope this helps. Spend the 30-40 bucks to get it checked for pulley, it will be worth it if you save the hundreds of $ to get the trans worked on and not be the problem.

Replying to: KUQUE (Oct 24, 2009 10:13 am) my suv when i drive it i willl hit the gas pedal the rpm's will go up but the car seems as if its idoling like im revving the engine in drive is the best way to describe it and i cant get the car to go over 40mph it seems. autozone checked my check engine lite and they advised that there was a problem with the coolant sensor however would this causethis type of problem. i also just had the battery replaced and the battery is only a few weeks old we checked the connection on the battery an they were not tight but autozone tightened them for me and it is still doing the same thing.do you think this is similar enough to what you went through ?

Replying to: trail03 (Oct 24, 2009 5:31 pm) My apologies, it is not called a engine fan pulley, but the fan clutch. you can see a pic of it at   http://www.am-autoparts.com/AM/Fans/Chevrolet/Trailblazer/-/AM-18868449/?utm_sou- rce=google_base&utm_medium=cpc&utm_campaign=new_google_base_feed   where are you located? you might think of calling these guys(very repuatable) here in my area, outsells the dealerships in replacement parts for ac/delco parts.   Full Service Auto Parts 1518 Mid Cities Dr · Pharr (956) 781-8983   see if they will ship to you. if not, contact me again and see what we can work out. if I am not mistaken, I got the part for a fraction of what the dealership was asking. good luck!
