SOURCE: diagram of a completely disassembled valve body for a 4l60e at

I don't know where you can get a free diagram, but there is a pretty good video on youtube of a guy disassembling the valve body of a 4l60e. Just go to youtube and search for 4l60e.

SOURCE: reset code trailer towing may set code gm 4l60E

Diagnostic trouble code P1870 (Transmission Component Slippage) is a General Motors-specific code whose set parameters are determined by transmission type and engine size. The PCM monitors and compares engine speed to vehicle speed after the converter clutch has been commanded ON in either high gear or Overdrive. Should the expected rpm ratio exceed predetermined parameters, DTC 1870 sets. And upon doing so, the PCM elevates the transmission main line pressure and stops converter clutch apply.

Once the vehicle has made it to a cruise state, the PCM then begins to monitor the vehicle's cruise ratio. If at some point the transmission begins to slip, P1870 sets and line pressure is elevated in an attempt to stop any further slippage and prevent further damage. This would explain why DTC 1870 Ls often accompanied by a complaint of a hard 1-2 up shift.

When this code sets, it could have any number of causes, ranging from the sump running low of fluid to a malfunctioning torque converter. Take a GM 4L60-E transmission, for example. When it's in Overdrive, the forward clutch and the 3-4 clutches are applied, as well as the 2-4 band. Now add the converter clutch. This is what the PCM monitors at cruise. If the ratio breaks away, the cause could be any of three components, the hydraulics that operate them or the electronics that control them. Fortunately, experience has shown that in most cases, the cause can be traced to some form of converter clutch failure as a result of valve body concerns. With GMs 4L80-E transmission, this code has usually been the result of a cracked converter clutch piston.

Put a line pressure gauge ($55 shipped on Ebay, or visit a local trans shop) on the pressure test port and go for a drive to verify proper line pressure. Base pressure at idle in P,N,OD should be around 70psi and around 140psi in R. Max line pressure should be at least 190psi at WOT in 1st or 2nd, 225psi is optimum. If base pressure is low, trans or pump is worn out. If max pressure is low, check EPC solenoid. If reverse is slow to engage, and line pressure does not come up to at least 130psi in reverse, replace the boost valve with a Transgo 0.049" - 0.500" boost valve (easy fix in pan), and replace the servo with an upgrade servo from a Corvette 4L60E. This will give you a more firm shift and address the DTC 1870 which is common to a weaken Boost valve or faulty EPC valve.

SOURCE: what model 4L60E tranny's can I put in my 1998

the way i figured which 4l60e works with my truck was to get the service number off of the ecm. Then I took that ecm service number and searched for it on ebay. People selling that same ecm will usually list what other vehicles that ecm works on. Then I went to the u-pull&pay and got a tranny out of one of those vehicles. I do know that after 95 there is an extra pin in the main wiring harness that goes to the PWM. My 94 tranny didn't have that pin. Also try pulling the main wiring harness out of your tranny and with a mirror look down into the tranny and get the pin configuration. Make sure the one you get also has that same pin layout.

Will the transmission from a 1998 chevy 1500 fit in my 2001 chevy 1500


The transmission in question is called, "4L60E" There are two versions. The 4L60E ran from 1992-1997. Then the 4L60E was updated and ran that version from (1996-2010). In 2002 GM introduced the 4L65E. So YES you should not have a problem fitting a 1998 chevy 1500 with a 4L60E into a 2001 Chevy 1500 with a 4L60E. You didn't mention that both were 2wd or 4wd. You can not convert a 2wd into a 4wd. I hope that helps, good luck.

95 G20 van transmission IN a 94 G20 van will it work and what would I need to modify to make it work thanks


4L60E 4speed automatic most likely. Very common in a multitude of GM products since the early 90's. Should fit with no modification. Best to measure your old tranny from bell housing to tailshaft and compare to the one you want to use. That way you can determine if your tranny mount and driveshaft will be a good match. Should be ok if they are both the same model tranny.

What is difference between a 1995 4l60e and a 1997 4l60e trans? can a 97 work in a 95?


I just answered the same question for another person. Physically the transmissions will interchange; just be sure to check ALL electrical plug's BEFORE installation AND change your linkage arm. The flywheel SHOULD be the same diameter also,just be sure to check the torque converter bolt pattern b4 installation. Lastly,be sure that the dip sticks are the same........ALL the part's on both transmission's are interchangeable,change as necessary.

4l60e tranny swap


No the 4l60e is a electronic transmission you need to find a 700r4 transmission which are very common. Check with your local junk yards and are pretty easy to install. About a full days worth of work for a person with general know how of vehicles.
