Hey Guys,
Im new to the forum, awesome site. Been doing some searches on the transmission fluid change I just did, got some helpful tips. But I ran into some issues after doing mine. I just bought the truck used, heres the info on it
2008 Chevrolet Silverado 1500 (Crew, 4x4)
5.3L
4 speed automatic electronic (4L60E)
68,000 miles
So being somewhat of an anal person, I decided to go through it and check all the fluids & change what I thought was neccessary. I changed out both difs with Amsoil SG 75w-90 (found this info on here, thx). Then decided to do the Transfer case & Tranny fluid change (gasket & filter pan drop). So I find out there is no drain plug on pan, WTH. Also, the shifter bracket is in the way & a pain to get off. Ok, getting back on track, change filter & gasket, fill pan with 5 qts as manual states. I used Vavoline Dexron VI full Synthetic. Take her for a test drive & everything seems ok except when I floor it, it wont shift into 3rd. It revs up then down slightly, at about 4-5k rpm. Then when I let off, it will go into 3rd. tried it multiple times and same issue. Tranny was warmed up when I did this, about 160+. It shifted fine when driving it easy. I go back home & check level on dipstick & it looks way overfilled. it looked almost double of where the full is on the Hot hasmarks. So Im thinking its overfilled, loosen pan & drain out to reach full on Hot hashmark. attempt to put into R & it wont engage. Crap, now its too low, fill it back up, guessing on where to fill to. I add about 1 1/2 qt and it engages in gear but seems to be rough when going into drive & reverse. its over the Hot hashmarks like before. I add some more, after calculating what I took out & put back in. I put in about 4 1/2 qts total, so according to manual once again, Im about 1/2 qt low. I know I sound like a rookie here, But Im not. So now Im wondering if the Synthetic fluid is too thin for this type of transmission, even though I have read about others experiences with Synthetic & it seems to be what a lot of guys are going with in their trucks. So maybe 3rd gear in my tranny is starting to go & now with fresh fluid in there, Im noticing it more. Now that Im thinking about it, I want to say there was a tiny hesitation into 3rd before but not sure, I have only had the truck for a week. IDK, what do you guys think? Any input would be greatly appreciated.
