I'm buying a 2005 Silverado 1500, 2WD, Z71 package, 5.3 L (327CC) Crew Cab next month and I'm wondering where I can buy a feesable and functional (proven) code scanner for this truck. As well, anybody know of good repair manual source for this truck. I won't be overhauling any tanny's but I would like to read the book or DVD and learn how to troubleshoot sensors and electrical stuff. I thank you all in advance.

Its impossible to dianose that problem without hooking a scanner to your truck and reading data lines. There are to many factors. But i can make a suggestion, if you have the 4L80E trans in that vehicle, try switching the input and output speed sensors. they are the same sensor, a faulty input speed sensor can cause a no 4th gear. If your symptons change then that is the problem..if not you need a scanner. they are located on the driver side of the trans on the side of the case

I have an 04 silverado with 90.000 miles
the trans slips shfting into second at slow speeds after it heats up.
if you accelerate fast it shifts fine.
i had it flushed at 75000 miles but they did not change the filter.
could the filter be causing this probloum.
thanks Joe

While the old filter could add to the problem, I think it was caused by the flushing. I've read many people having problems with somewhat high mileage doing trans flushes. The reasoning behind it was that the "flushing" dislodges gunk, which you would think is good, but not in all instances causing more problems at times than it solves.
I'm surprised that they would reinstall the old trans filter. I mean its the same as changing your engine oil and leaving the old filter in place.

I bought my chevy silverado 00 new with the 5.3L and currently have 193,000 miles with zero problems to report about the transmission or motor. Plus the original spark plugs are still running great and gas mileage is still around 18 mpg combined city/highway. Plus I routinely overload the bed...I've had over 4000lbs. in the bed a couple of times too.

I've had my chevy 00 since new with the 5.3L and valvoline flushes my tranny every 50,000 miles. I routinely overload the bed and currently have 193,000 miles and the tranny still feels brand new.

Just so you know..a flush service and a transmission service are not the same. A flush is where a machine is attached to the cooler lines, replacing the old fluid with new fluid. This does not include changing a filter. A service is where the pan is removed and the filter is changed and sump is cleaned out. Late model 4L60E's have plastic 1-2 accumulators that can crack...also in 2003 gm went to a new style epc solenoid that has causing pressure problems at low mileage.

92 Chevy k1500 4x4 Transmission problem

Intermittent problem with truck kicking into gear after setting for a few hours or over night. Sometimes when I start the truck and put it in gear it takes right off. Other times it does not kick into gear and just revs up when I give it gas.
Could it be a clutch or oil pump problem? Or do I need to get a transmission job.

What do you mean the dealer can't tell you whats wrong? A faulty mlp sensor can cause that also a speed sensor. But usually are very easy to detect and diagnose. But You may have a different problem. I suggest you take it somewhere else if they are not capable of diagnosing the problem.
