I have a 94 chevy Silverado 5.7l with 4l60 transmission will a 97 chevy Silverado 4l60 work even if the speed sender is on different side and made different on transmission

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.

It should be a chevy T5

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.
