The engine size is 6.0L LQ4. Transmission is 4L80E I plan on waiting for the business to get consistent work or guarantee contracts with local companys then go buy a 3/4 ton cummins/duramax. My friend has a ram 3500 cummins, he will let me borrow when i need it

I’m planning on bumping up the gear ratios on my 1500HD i believe it has 3.73 gears and limited slip. The reason for this is because it is sitting on a 6in rough country lift and 20x12 on 33x12.50R20. It lacks power of course, I’m finally ready for this upgrade, as i have gotten my...

Kinda hard to tell looks like they had repainted the torque converter similar to the color it was when I brought it brand new... I just got home stopped by friends shop to talk to him I told him i got a problem the transmission doesn't have oil pressure, no reverse gear, forward gears. he told...

I didn't do that didn't think of it, but I marked my initials on the TC and got it back with my initials on it, the trans looks the same color as i got it in the first place I don't suspect that they swapped it.

@Will L. I would name the shop but the connection to this transmission builder is through a diesel mechanic friend of mines. He told me "His guy is good never had issues with him" I asked my friend the other day what's the name of his shop and he told me he doesn't work for anyone he does it...

So i went ahead and double checked that it had trans fluid at the proper level today for 10mins before leaving to class. I went through the gears then back in park. Added a quart and half or so while idling. and its right below the Hot level mark the second from the bottom. I put it back in...

Heres an update I got my transmission fully installed today poured in a gallon of trans fluid is all it took so that tells me the transmission guy didn't full take it apart to see what was the issue with my transmission I started it up and watch my pressure gauge slowly go up to about 55psi...

Gave Jake's Performance a call they told me that the "sweet spot" is 0.160. So I'm good now. I guess this thread can be helpful for others wondering what to do. they told me if it were to be more than 3/16 of a inch they put flat washers about 0.040/0.060 thick washers between the converter...

I have a 2001 Silverado 1500HD with the LQ4 6.0L Iron Block, i recently swapped my original 4L80E for a diesel because my the old trans a lot of the hard parts had serious overheating on the surface with just surface cracking and i lost reverse gear. i sent the diesel trans out to get rebuilt...

So i just dropped the pan here do you guys think some of this stuff in the pan is normal? i did see alot of shiny particles in transmission fluid very fine particles. I also took a picture of the valve body any idea what year this narrrows it down to?

I spoke to Jake's transmission and asked them what is the recomended overall shift pressure he told me depends on HP . i told him its a stock 6.0L with "REBUILT" transmission with their rebuild kits he was saying 120-130psi is too low, that theres internal pressure leak, mabye the clutch seals...

My truck came with with 4l80e originally. i swapped it out for a diesel 4l80e not sure what year to be exact but def a late model case as it has the transmission lines futher apart from each other. Looking at the charts after im done typing this.

So i went ahead and brought a engine oil and transmission oil pressure gauge kit from harbor freight. I drove the truck locally with the gauge. I have some gopro videos that this forum won't let me post if you guys want to see the video message me your email and I'll send it. When the truck is...

on the way back about 45min drive. i WOT 3x times before it jumped from 150 to 177F and if i go out to the desert it'll come up to 200F. I forgot to mention that my shift firmness throughout all the gears are not even firm feels like cvt transmission shifting if you know what i mean only way i...

How would i try to find a air bubble? would a transmisssion flush remove that issue?

So i removed the line and started it up the pressure line puked about quart and 1/4 of transmission oil in bout 5seconds at a steady flow now too much that the hose would fly out of the bucket i had it in. i also pulled the fitting and it threads nicley into case and appears to be the right...

I'm not sure what year core i will try to find out today and not sure if he used the pump that came with this trans or the one from my original. it does have the same location fittings as my original one and i'm not sure if he used the new fittings that came in my kit for that. I did order on...
