Mannual Tranny Swap Options Options

[erahman85]

From my understanding and research there are several different transmissions that fit the 5SFE. My car has low miles and when It gets a little older I will most likely put in the 3SGTE. For now I want to go from A/T to M/T and I have been advised that there are two different transmissions to consider. One that originally came with the 5SFE and one that goes with the 3SGTE but both fit the 5SFE. Obviously if I want to swap engines later, I should get the turbo tranny. Whats the difference, with what numerical designation do I look it up with and are there any differences betweend the trannies in the 1st, 2nd, and 3rd gen 3SGTE?

Just go with a GT manual trans. It will save you the headaches. You can use the GT transmission as well on the 3s swap.

If you are asking about the 3s trans from the Celica models it will not work. You are talking about bolting an AWD trans to FWD.


Go with the S-54 trans from the GT. Life will be easier.

yea that or you might consider a tranny from an mr2. not sure of the model number but it is common to use when doing the 3sgte swap as well, and should hook right up to your 5sfe u have right now. oh and you might consider turboing that engine. its got a lot of potential as presure2 has found out... just my 2cents though

i on the other hand.. got stuck w/the ****ty 7afe and will most likely drop in a 20valve 4age or 4agte (if i have the cash)

hey thanks for the info. I put that on google (s-54) and came up with the following:

The MK2 Mr2 was sold between 1990 and 1995, during which time it was offered with 3 available motor/transmission combinations.


1. The 5SFE 2.2L DOHC non-turbo engine with S54 Transmission

2. The 3SGE 2.0L DOHC non-turbo engine with S54 Transmission

3. The 3SGTE 2.0L DOHC Turbo engine with E153 Transmission


The Toyota E153 Transmission is a 5 speed manual transaxle that drives all MK2 Toyota MR2 Turbos between 1990 and 1995, and is bolted up to the 3SGTE 2.0L DOHC Turbo engine. This should not be confused with the S54 Transmission that was offered on the Non-Turbo Mr2 between the same years.


Limited Slip VS Open Differential

There are two variations of the E153 transaxle: The Standard Open Differential Transaxle, and the Viscous Coupler Limited Slip Differential Transaxle.


On the E153 Transaxle, the Limited slip transmission can be easily identified by removing the axles, and looking through the axle holes on the transmission. If the transmission is equipped with the factory viscous coupler type limited slip, there is a bar that is visible inside of the hole.


There has been much debate over the meaning of the bar because on most transaxles it is the abscence of this bar that indicates the presence of a limited slip differential, and the presence of the bar that indicates an open differential. In fact, even on the S54 transaxle (used on the non-turbo MR2) which does not have a limited slip differential, this bar can be seen through the axle holes.


In fact, the bar itself does not in any way contribute to the limited slip feature of a viscous coupler differential. However in the case of the E153 transaxle, it can be used as an indicator to determine which differential is installed in the transmission.

This is illustrated in the Toyota repair manual excerpts & photos shown below:


E153 with Viscous Coupler Limited Slip Differential E153 with Standard Open Differential


Note that the bar we are looking at is actually the “pinion shaft”. Note that there is a hole inside the “differential spider”. This is the hole we are seeing when we look through the axle holes.


Compatibility with other motors & Axles

The E153 transaxle can be easily bolted to the following engines


5SFE & 3SGE

The E153 transaxle can be bolted to the 5SFE motor or 3SGE motor without issue. However, the E153 Axles & Hubs must be used.



Variations between 1990 and 1995

Speed Sensor

The E153 Transaxle used a mechanical speed sensor from 1990 until 1992. After 1992, an electric speed sensor was used in its place. Either sensor will fit into any year of the E153 Transaxle

you can use the mr2 e153 in ur swap, look up the stickies.
