I did some work on the '00 XJ today. Including: battery terminals,
serpentine belt, idler pulley, transfer case fluid, transmission fluid &
filter, spark plugs, and pulled and cleaned the throttle body.

I used Valvoline full synthetic ATF+4 in the transmission and transfer case.
The question I have is.. I'm not sure if the previous ATF+4 that remains in
the transmission was full synthetic or not. Is all AT+4 full synthetic? Will
I have a problem with having half and half (full synthetic and on
synthetic)?

We also tried to do an alignment (my toe was 1/4" in at the front), but
despite our best efforts, we were unable to break the tie rod ends free
enough to adjust it. I'll pay the $65 to have it done.

Thanks,

Carl

 

Isn't that what the synthetic blends you find on the shelf everywhere
are? Just a synthetic mixed with a conventional... I don't see any
reason it would hurt, but I've never owned an automatic, so don't hold
me to that.
