1. What is the recommended tire pressure? GM says it should be 30psi but Jiffy Lube recommend 35psi. I have just replaced all 4 tires to the Dayton UNI-T. Any comments on that?

Go by what's on the sticker on your door.


2. I went to GM to have my fuel filter replace but was told that the clip was broken. I have to buy the whole fuel sending unit (part#25317984) and will cost me over $500 (parts & labor) to have it replaced? Is that justify? It is a lot of money. Will driving with a old filter damaged the engine???

Have them show you the broken clip. If they're talking about the small clip that holds the filter to the line, that is total and complete BS!!! It's no big deal to change this yourself - especially if the clip is already broken. That thing is a pain in the but to get off. You'll see what I mean if you want to try to change the filter yourself. A regular hose clamp would work just fine. And if you buy a filter at a store, you'll need to remove any connectors already attached to the filter. If you don't want to do it yourself, I'd definitely take it somewhere else that won't try to screw you like this.

3. Tranny fluid change? I went to GM and they says that it is not necessary (I have 66000 miles) They recommend that a change @100,000 miles for my model??? I have read in this forum that change every 30000-50000miles.

Unless you're having problems or are wanting to go synthetic, you really shouldn't have to change it.
