Almost to 100K miles

[Chris97K1500]

My truck is at 95K miles and will be at 100K in a couple months, but with dental school starting back up, I won't have time then. I have 2 weeks now to work on my truck. What should I do as far as to maintain it. I got this truck at 82K miles in Feb. So I don't know exactly how the previous owner maintained it, all I know it drove perfectly. I've already changed spark plugs, I do the oil every 3K miles, front brakes replaced, rears are next week, other than that, I haven't touched anything else. Just want to make sure I don't overlook anything. I'm thinking about draining the AT fluid (what's in the pan) and refilling it. Change the differential fluid, I read something in the search feature that I should not use synthetic fluid in my diff due to the type of gasket that came on my truck. I was going to change the gasket as well. Any other definite things to check or change? Thanks, Chris

That seems pretty good, but I would check the transmission fluid also.

Sounds like you got it covered. I had a 98 suburban 4x4 and changed it all over to Amsoil synthetic, diffs and tranny as well as engine and T case. No problems at all. Don't forget the fuel filter and air cleaner, pcv as well. If you want you can even go as far as to change out the power steering fluid. That is an easy thing to do. Just suck it out with a turkey baster and refill with fresh.

I think you have it pretty well covered from the sounds of it.

 

btw, how difficult was/is it to turn everything over to Amsoil synthetic? I'm gonna need an oil change soon and want to do it myself and thinking about buyin some Amsoil to run in my truck (98 Z71 ext cab 1500).

Best way is to get some auto-rx.com and follow their directions. Then get some of Amsoil's engine flush and do that. Then put in the synthetic. First product cleans slowly while driven, amsoils stuff cleans in 15 minutes w/o driving, drain completely and put in the good stuff.

Bigtruck21 hit it right on the head.

 

Not hard at all to switch it over. The fluid changes are pretty straight forward and if you check out the guides here in the forum's main home page they have some really good detailed instructions sent in by a few indiviuals on here with pictures an all.

 

If your interested in Amsoil just let me know. I can send you a catalog and product information. Depending on where you are in the country you can get it delivered as fast as a day. There are distrobution centers all over to name a few one in Dallas/Fort Worth, Las Vegas, Richmond Va, Orlando Fl., Lancaster Pa. and the main office up in Superior WI.

 

The Auto RX will do a really good job at getting it clean and ready. That stuff is great. I have had great results with it and a few I know that I got it for and tried it.

You can get it off the web just click here.

I'm at 157k not the original owner, but I'm pretty sure tranny fluid never been changed. I check it and keep it filled properly and tranny never under stress, and never seems a problem. Should I change?
