    FFM Heater

    Leroy is out of stock on the heater for the FFM. I found this one on Amazon: WIX Filters - 24922 Heavy Duty Heater Kit. It looks identical to the picture in Leroy's store but I can't find anything confirming it is the same one. Does anyone know if this will work in the stock 6.5 FFM?

    4L80E won't shift until it is warmed up

    Problem solved. It was the ignition switch again. It just had me confused because it so predictably would work after it warmed up. The switch wasn't that old either, it didn't last nearly as long as the original one did. Sent from my Pixel XL using Tapatalk

    4L80E won't shift until it is warmed up

    Fuse is 10 amp and doesn't blow. I'll look into power. Scanner says system voltage is 13.1, idk where is picking it up though. Sent from my Pixel XL using Tapatalk

    4L80E won't shift until it is warmed up

    How do all the dash symptoms happen as soon as I switch on the 2-3 solenoid? I see the ECM calling for 2nd gear on my scanner and everything is working when I'm in 2nd, as soon as I hit the 2-3 switch speedo & tach go to zero, check gauges on, gear indicator off. That's when it's not shifting...

    4L80E won't shift until it is warmed up

    I did that it was 12V, that doesn't rule out intermittent though. Sent from my Pixel XL using Tapatalk

    4L80E won't shift until it is warmed up

    My truck intermittently started having erratic speedometer behavior, a flickering check gauges light, no gear selection light, and occasionally no tach. I thought my grounds were going bad again so I cleaned them up and checked voltage drop across them and they were good. After about 10,000...

    No shift until transmission is warm

    I should have posted this in the transmission forum. How can I move it?

    Rebuilding injectors

    Thanks, not much on ebay just now, 2 from Latvia and 1 from Australia, and $45 each. Might as well get the set of complete injectors from Leroy.

    Rebuilding injectors

    Where are you finding the nozzles? Rock Auto is only showing 1 available, Summit & O'Reily's have none, and most of the other Google results are ebay or Chinese web sites. I'm not confident in getting genuine Bosch from them.

    EGT Too High

    Thanks for all the feedback, I'll just do 3rd gear when needed and keep EGT below 1050° and watch ECT. I feel more comfortable now knowing it can run that hot. I towed the trailer again, loaded this time to 3600 lbs, and the same area that I first noticed the 850° the other day got no hotter...

    EGT Too High

    The hills I climbed yesterday were probably nothing over 5%, but some were several miles long. Putting it 3rd at 60MPH kept the temp around 850. When I do the move I'll have to get over a few of those burned up stains climbs. It sounds like 850 isn't so bad and the highest I let it get was 950...

    EGT Too High

    Thanks, I was watching that too, it never went above 195°.

    EGT Too High

    I haven't pulled it before and boost when I first noticed it on the flat was at 6PSI, climbing it would go higher, it goes as high as 15PSI under hard acceleration. When I slowed a bit to bring the temp down boost was around 3PSI. My pyro gauge red arcs at 1050° so I guess I'm still ok.

    EGT Too High

    Yesterday I was towing an empty cargo trailer, about 1400 lbs, on nearly level ground at 65MPH and my EGT went right to the top of the green arc, 850°. When going up a hill I had to slow down and downshift to third to keep it there. Occasionally I let it go into the yellow arc to about 950° to...

    Troubles with Turbo

    I did not replace the oil cooler, the one I have was pretty new and after the old motor failed I had my oil analyzed, not from the filter but from the drain plug, and it came back with <.1% water contamination. I did have 38ppm Silicon (labeled as Moderate abrasive) and 1663ppm Calcium (labeled...

    Troubles with Turbo

    I think I've got it as good as it's going to get. In the past I had to cut off the end of my upper intake to install my ATT. When it failed and I had to go back to my GM4 I used a piece of 2.5" silicone hose to connect the cut off piece back to upper intake and I only used one clamp directly...

    Troubles with Turbo

    I looked for boost leaks and everything is tight. I didn't put any sealant on the turbine side of the center section, it didn't look like any was there originally, it doesn't look like there is any exhaust blowing by there. I'll check the v-clamp when I get a chance but there are no new exhaust...

    Troubles with Turbo

    It spun very freely, the old one still spun easily but you can hear something rubbing inside, I assume its a bearing going bad unless its the oil seal. The noise it was making is the reason I replaced it. I spun the new one from the air inlet also after assembly to make sure it wasn't rubbing...
