Sounds like something is wrong with either the shifter or the shifter cable.

- AMSOIL Oil Filters

  Hey everyone, I just wanted to keep you updated on AMSOIL's oil filters. Their filters will be back in stock shortly and some already are so you will have to check to see if the ones you use are. Most will be back in stock the first week of August. Mainly I know most on here probably use the EaO17, that one is supposed to be in stock the first week in August. But be aware that once it is, it might be out of stock shortly after since there will be a rush of orders getting in. AMSOIL has found a new manufacturer and has been working with them on making their filters and been going through quality control for a while to make sure the filters are up to AMSOIL's standards. This is why it has been taking so long. As always you can order at https://syntheticadvantage.com Also if anyone is interested in my GM-Trucks special send me a PM. Plus if you want to save up to 25% off retail, become a Preferred Customer, you can apply here. https://www.amsoil.com/p/preferred-customer-registration-preg/?zo=521390

  Mine runs 145 to 158 ,95% of the time. ‘25 1500 with 5.3 and nht option. Wonder how long it will last? Wonder how much water is in the oil? Bought it in Oct 2024. This was today in south Louisiana.
