So it's been quite a while since I've been on here but my truck has started acting funny. Months ago I had a problem with the tcc not locking up, I changed the fluid and filter along with the speed sensor on the side of the trans cause I had a code for it and all was good. Then last week I noticed when the tcc locks up its only dropping maybe 159 rpms. I used be doing 53 mph at 1750, now I'm at like 48 or so. Checked a couple days ago and the fluid is fine and no codes. Well on my way to work I noticed that it won't lockup in 3rd but kinda does in od. Got to work and I've got a p0740 code which I know is the tcc lockup. This trans was rebuilt about 15k ago by a very reputable guy. Also maybe unrelated but every now and then right after start up the truck will idle very low and it sounds like it has a monster cam in it. Pop the gas pedal and it goes away and is fine. The iac should be clean because I cleaned it when I put the new tb on it about the same time as the trans. I have heard of the tps doing weird things with the tcc just wanted some incite.
