How-To: Remote Spin-On Transmission Filter Kit.

Recommended Posts

Yup.  Still working great.  I'm at 80k.  I've been doing the filter change at least 1x every year.

Old thread, but I used the same Derale kit as you. I installed mine last week above the 2nd battery tray. Tied in the line where it comes out of the radiator and goes to the condenser. Cut that line, flared the ends, used 3/8" trans hose and some SS hose clamps. I used Swagelock SS fittings on the Derale block. Seems to be good to go. I'm using a FL1A filter, not sure its tight enough micron, though. I also bypassed/plugged the thermostat housing on the transmission, and welded a 3/8" NPT bung on the trans pan so it has a drain now. I bought the new pan and filter on Amazon, going to weld my a drain plug on my old pan for my brother to use in his Sierra.  SMH at GM for not having a drain plug on their pans....

Glad to hear my old post helped.  I'm at 87k and still running the trans filter kit.  I replace the filter 1/yr. Trans fluid looks great and the tranny is running great.

Long term update.  I'm at 93k and still running this trans filter setup.  Not one leak.  I was doing 1yr/20k intervals on the filter but this past year have been lighter on mileage and busy.... was supposed to change at Christmas break, but didn't.  So I'm about 14 months and 20k on the current filter.  Looking to do a full trans service at my next LOF of around 97k.  Trans pan filter, spin-on filter and fluid. Love this setup and would do it again. The 1269 filter is much smaller than the cheap "flush" filter I started with which was a full-size FL1A or whatever oil filter.  Thing was the size of a house.  The 1269 is tucked nicely up in the rails.

I moved my mount to the cross brace near the brake booster. The coolant reservoir for the supercharger mounts to the secondary battery tray. I've switched to a FL400S since the filter is smaller.
