Tahoe Maintenance Question

[kashrahman]

So in 2008 we bought an 05 Tahoe, with 21K miles. I've tried to do fairly comprehensive maintenance on it, despite it's low usage. My question is: am i missing anything so far?

Synthetic oil change

 

we plan on more driving this summer, probably 7-8K miles, so my plan for this fall is:

- synthetic oil change, replace air filter, ? change power steering fluid.

 

and what about trans fluid/filter? I thought I had read somewhere to change every 100K miles, but we'll never get there at this rate. (and I could have sworn I had it done in 09, but looks like I didn't) if i go by time, how often should I change it?

 

thanks!

I personally believe 60,000 mile is proper for the transmission. I believe you got everything else covered. Maybe check the belts.

thanks! i guess my main concern is keeping up with maintenance by time versus mileage; averaging about 6000 miles/year so even that means 10 years before a transmission fluid change. thoughts?
