Washi Posted December 20, 2012 Report Share Posted December 20, 2012 I have 2003 Chevy Silverado I bought this summer. Lately I noticed I have to drive a minimum of three miles once I get on the highway before it will shift into overdrive. It has taken as far as five miles. What could be causing this? I haven't been able to check the transmission fluid after it is warmed up because I can't reach from my wheelchair. I did have someone pull the dipstick while it was cold and it looked really high up on it. Is it posible it is just too full? Luckily I did buy a warranty and I plan on taking it to the dealer as soon as I get a chance. Thanks in advance for any help. Quote Link to comment Share on other sites More sharing options...
Ravin R10 man Posted December 20, 2012 Report Share Posted December 20, 2012 my '98 has 182K it will hesitate also..but only at the time it is suppose to shift up.. in temps below 20 it will not slide into reverse until it warms up OR you can drive forward 50 feet..then it will reverse..I park it for forward travel in the cold no prob. seems people do not want to buy it..even at $1500..Ive got more than that in news parts invested..may just take it to an auto salvage, they offered me that much or keep it and use it for a way back home from fields and deer hunting Quote Link to comment Share on other sites More sharing options...
Shaun_300 Posted December 21, 2012 Report Share Posted December 21, 2012 Are you getting the guy to check the transmission fluid when it's running or engine off? Transmission fluid has to be checked with the engine running, or it will read too high on the dipstick if you check it while it's off. In colder weather the PCM will delay the torque converter clutch from locking up until the coolant temperature comes up, just so the engine can run at higher RPM to let it warm up faster, which is normal. All depends on the outside temperature and how cold the coolant temperature is when you start it cold, I see your in Missouri so I'm assuming it can't be that cold yet, but I could be wrong.

Washi Posted December 21, 2012 Author Report Share Posted December 21, 2012 (edited) It wasn't running. I just had someone pull the dipstick because I have seen some vehicles that have marks on the dipstick for checking it both ways. I think when I first noticed (when it took three miles) it was in the 60's (Fahrenheit) and the times it took extra long to kick in (five miles) it was probably around 40. It just seems like too long. Edited December 21, 2012 by Washi Quote Link to comment Share on other sites More sharing options...
Shaun_300 Posted December 21, 2012 Report Share Posted December 21, 2012 Check it when it's running, there will be an add, cold, and hot mark on the dipstick, it should be between the cold and hot mark at all times. Could just be the cold weather causing it, if it doesn't flag a check engine light I wouldn't worry about it. I know dad's 2001 Silverado won't even shift out of 2nd gear in town when it's cold between 15 and -30F (approx) until the coolant temp gets to a certain temperature. It'll sit and rev 2800rpm in 2nd gear around town til it warms up enough before it'll shift into 3rd gear. Quote Link to comment Share on other sites More sharing options...

LETMGROW Posted December 21, 2012 Report Share Posted December 21, 2012 You said you have an extended warranty on the truck. How much time do you have left? How did the fluid look when you checked it? It should be red, not dark brown or black. Does it smell burnt? If it is dark or smells burnt this is a sign things are going wrong. I'm not big on recommending trans. services unless it is being done regularly to start with but it may be time for a fluid and filter change.

Washi Posted December 21, 2012 Author Report Share Posted December 21, 2012 I have about two and a half years left on the warranty. The trans fluid looked good but I didn't think to smell it. Quote Link to comment Share on other sites More sharing options...
Shaun_300 Posted December 23, 2012 Report Share Posted December 23, 2012 Overlooked that you had warranty on it, definitely worth taking it in to see if they find anything, they'll probably recommend leaving it overnight so they can roadtest it when it's cold with the scanner to see what's going on.

LETMGROW Posted December 24, 2012 Report Share Posted December 24, 2012 What clock are you talking about Lynn?? The weather ticker in my sig? Yeah, I swear it was an hour fast when I looked at it the other night. OK now though. Hate to admit I was wrong, maybe I was though. It happens.
