Introduction
So imagine you've bought all of the bolt-on power adders for your car: a cold air intake, header, exhaust, programmable ECU, cams, and maybe a few other bells and whistles. Dyno pulls are telling you that you're making decent power, but you can't seem to get the 1/4 mile times that you should be making. Assuming there isn't a large margin of driver error, you may want to look into replacing your stock open differential with a Limited Slip Differential. By this time, you're probably pretty tired of shelling out cash for performance upgrades. That's understandable. The good news is that with a small set of tools and some patience, you can install your new LSD yourself.
This article specifically describes how to install a Wave Trac LSD (made by Auto Tech) into a 5 speed RSX transmission, but the general process is very similar for most FWD manual transmissions. The process described below is nearly identical to the way a Honda technician would do it, and we've included ample illustrations to make the process as clear as possible.
Before you begin disassembling you transmission, find a flat, clean workbench to work on. You'll want to carefully lay out all of the parts as you remove them so that you can keep track of them for when reassembly begins. To properly assemble the transmission, the tranny should be placed on the workbench with the input shaft facing down. Use wood blocks to lift the bellhousing up so that the input shaft is not touching the bench. Note: Make sure that all fluid has been drained from the tranny before disassembling it.
Follow the black text in steps 1-16 for disassembly. For reassembly, follow the steps in reverse and refer to the red text for torque specs and other important information.
-
-
Remove the (3) ball spring detents using a 12mm socket. These are what keeps the transmission in gear after you've shifted. Handle these with care as they tend to fall apart when removed.
-
-
-
Remove the backup light switch using a 27mm socket. Unbolt (using a 12mm socket) and
-
Remove the vehicle speed sensor and its o-ring. You may have to twist the speed sensor back and forth a bit to get it loose.
-
-
-
Remove the interlock bolt using a 7mm allen wrench.
-
Reassembly Tips: Apply Honda Bond to the threads and torque to 29 ft-lb (39 N-m).
-
Unbolt and remove the shift lever assembly and the two dowel pins that line it up with the transmission case.
-
-
-
Remove the 10mm flange bolt using a 14mm socket.
-
Remove the drain plug (using the end of a 3/8" socket wrench or extension) and filler plug (using a 17mm socket).
-
-
-
Using a 12mm socket, remove all of the 8mm flange bolts that hold the two halvs of the tranmsission together.
-
-
-
Remove the 32mm sealing cap using a 14mm allen wrench.
-
Scrape off any Honda Bond that is on the mating surfaces between the sealing cap and the transmission.
-
Use a set of snap ring pliers to expand the 72mm snap ring and remove it from the groove it sits in on the coutershaft bearing. The snap ring can not be removed from the tranmsission at this point. It only needs to be removed from the groove it sits in.
-
-
-
Using a pry bar, gently pry the two halves of the transmission case apart. Lift and remove the upper half of the case. Before moving on, use a razor to scrape off the HondaBond that was sealing the joint where the two halves of the case met.
-
-
-
Unbolt and remove the reverse lock-out cam using a 10mm socket. This only applies to the 5 speed model as is shown here. 6 speed models do not have this part.
-
-
-
-
Unbolt and remove the reverse shift fork using a 10mm socket.
-
-
-
-
Wrap the input shaft's splines with masking tape. This is done to avoid damaging the input shaft seal as the gearset is removed.
-
-
-
Remove the 28mm spring washer and the 28mm washer that were sandwiched between the mainshaft and the mainshaft bearing.
