4L60E Transmission Rebuilt ' eBay
SOURCE: change drivers side door panel on 94 chevy p.u.
unscrew the inside handle and pop of the window arm....then slowly work your way around the panel poping loose the plastic rivits on the inside edge...lift panel upwards to unhang it from window lip...thats the plastic panel...the metal panel inside that is pretty self explanitory..unscrew and take off the clips holding the controle arms to it and remove...do use caution as parts are very sharp and will slice your fingers and hands.

IF BOTH TRANS ARE THE SAME,THEN YOU SHOULD HAVE NO PROBLEM

It should fit, just make sure you have the right year 4L60E and change the boost valve rating. Too low of a boost valve will cause you to burn up your transmission when it's making gear changes a good boost valve for your Silverado is a 0.490" or a 0.500" boost valve like the ones in a Corvette or Camaro to take the extra stress of HP and tq the 5.7 has above the 4.3 liter engine.
The key distinction of the Later 4L60-E (1997-2006) from the Early 4L60-E (1992-1997) is the six-bolt "hex" rear output or tailhousing / adapter pattern. The previous versions featured a four-bolt square bolt pattern at the adapter or tail-housing. Additionally, the removeable bellhousing is also another distinguishing feature.
Two-wheel-drive versions have tailhousings and typically a longer output shafts than four-wheel-drive versions, which have various adapter assemblies and a shorter output shaft. 4L60-E is found in nearly every GM rear-wheel-drive application, including the C/K Truck, Sonoma, Jimmy, Tahoe, Yukon, Astro, Safari, Suburban, Bravada, Firebird, Camaro and Corvette.
The 4L60E is now concurrently produced along with its strengthened progenitors; the 4L65-E and the 4L70-E. They share most components and improvements together. The 4L65-E was introduced in 2001 as an HD version of the 4L60-E. It has a stronger planetary and a strength-improved output shaft.
4L70-E transmission is a further improvement still, and share most components. However, these versions have strengthened and improved components for the significant power outputs of GM's impressive line of Gen III + engines.
Good luck and you have a 4L60E transmission, thank you for using Fixya

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 0.490" boost valve
(easy fix in pan).
Slow, slipping or no reverse: "lo-reverse" clutches are worn out,
fluid leak in the reverse apply circuit, or broken sunshell. It is
possible to remedy a fluid problem by removing the checkball from its
cage in the case in the rear of the trans may help (must remove
valvebody), or adding a high-viscosity additive such as Lucas
Transmission additive or other seal restorer product. May also have worn
boost valve (can replace in the pan)
From what you have described, it may just be a broken Sunshell which is the weak point to the 4L60E transmission. Gm had a upgraded program to lower the transmission line pressure when revers is engaged to keep the Sunshell from breaking when put in to revers.
Thank you for using Fixya and keep us posted

Did you ever get this figured out I have a 97 with a 94 I want to install in it cause the original went out and idk what I need to do to make this transmission work
