The G57 5-Speed manual This was used on 2WD models with the 22R engine. 1st 3.704, 2nd 2.020, 3rd 1.368, 4th 1.00, 5th 0.854. Reverse: 4.472.

The G58 5-Speed manual

This was used on 4WD models with the 22R engine. It is basically a beefier version of the G57: 1st 3.928, 2nd 2.142, 3rd 1.397, 4th 1.00, 5th 0.851. Reverse: 4.743.

The R150 5-Speed manual

This was used on 2WD models with the 3VZ-E engine. 1st 3.830, 2nd 2.062, 3rd 1.436, 4th 1.00, 5th 0.838. Reverse: 4.220.

The R150F 5-Speed manual

This was used on 4WD models with the 3VZ-E engine. 1st 3.830, 2nd 2.062, 3rd 1.436, 4th 1.00, 5th 0.838. Reverse: 4.220.

The W46 4-Speed manual

I believe this one was only used on 2WD models with 22RE engine:
 
  1st 3.954, 2nd 2.141, 3rd 1.384, 4th 1.00. Reverse: 4.091.

The W55 5-Speed manual

I believe this one was only used on 2WD models with 22RE engine:
 
  1st 3.566, 2nd 2.056, 3rd 1.384, 4th 1.00, 5th 0.850 Reverse: 4.091.

The W56 5-Speed manual

This tranny was used in 4x4 models with the 22RE engine:
 
  1st 3.954, 2nd 2.141, 3rd 1.384, 4th 1.00, 5th 0.850 Reverse: 4.091.

The 3-Speed automatic

Need to look up the model number and the gear ratios. This transmission is a normal three-speed hydraulic automatic transmission. Most of these units serve faithfully, but are not reccommended for hot climates--- they have a reputation of overheating problems, especially in desert climates. I haven't heard anything about tranny coolers on them.

The A43D 4-Speed Automatic Overdrive Transmission

This automatic transmission was used in 2wd 22RE models: 1st 2.452, 2nd 1.452, 3rd 1.000, 4th 0.688 Reverse: 2.212.

The A340E/A340F/A340H 4-Speed Automatic Overdrive Transmission

This is Toyotas ECT (Electronically Controlled Transmission) automatic. It is used in both 22RE (4wd) models and in the 3VZ-E and 22R-TE (both 2wd and 4wd) 1st 2.804, 2nd 1.531, 3rd 1.000, 4th 0.705 Reverse: 2.393.
 
  The 4WD version (A340H) has a transfer case with low-range gearing of 2.659:1 Models designated A340F have (I think) the VF2A transfer case with a 2.566:1 low range  Someone who asked to be anonymous sent the following info: The codes breakdown is as follows A 340 H A = automatic transmission 3 = 3 series 4 = 4 speed 0 = gear ratio / minor change H = hydraulic transfer case (includes ECT) F = mechanical transfer case (includes ECT) E = Electronic Controlled Transmission (used on 2WD 4Runners, other 2WD Toyota vehicles) This transmission uses 2 solenoids to control the shifting. solenoid 1 solenoid 2 1 th = ON OFF 2 nd = ON ON 3 rd = OFF ON 4 th = OFF OFF The throttle cable is used for line pressure, it can be disconnected and the transmission will still shift normally. But if youloose power to your 2 shift solenoid, you will be taking off in OverDrive. What you should do is : Select LOW 1 . (1 st gear) then 2nd ( 3rd gear) then D (over drive)

I have a Toyota 4X4 with a 5 speed manual transmission. I was wondering if there was any kind of marking tags (identifiers) on it. I believe it is a W56. Would a G58 fit bell housing and transfer case without modifications.
