Sorry for late response, got caught up in work, by a gm reman do you guys mean a gm rebuilt transmission only or like at an auto parts store?
my advance auto parts store is selling a rebuilt 4l80e by a company called shift pro by ETE $2,359.99 plus a refundable core charge of $800 they also have...
Here are some pictures of disassembly thru reassembly. also not the last picture shows that the rear center support bolt the 2 hole passages are not plugged up.
also where could I apply compressed air on the case side to see if 1-3rd gear clutches are engaging and disengaging? also I replaced...
This a new issue from my last old thread when I had the transmission rebuilt and was having issues with no/ or low oil psi, and overheating. I put about almost 24k miles since. That is until recently I was hauling a Lincoln town car lowrider driving back home from Ontario, California.
I got off...
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...
No not a ball check just a magnet on the other end of my snap on flat head. that some stuff it pulled out from the magnet also i relaized that the magnet was not in the correct location where stock recomended
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...
Sorry guys moving a bit too qucik here between post. So the snap on scanner is reading TCC SLIP SPEED up to 500rpm while i am starting from a stop 0MPH-60MPH once i get up to 60MPH and its in final gear TCC locks up and scanner now reads 0-3rpm slip ONLY when the TCC locks up. I will try later...
