Topic: stupid trany question

[4DEES]

I feel stupid asking this but oh-well.................
I got a 95 tranny and t-case(4cyl.)which t-cases are the same? 89-95 maybe?does this question make sense?

[kyle_22r]

if it's from a 4 banger, it's either the W56 and RF1A(gear drive) case, or the G58 tranny(bad juju, can't adapt anything to it).  did the truck have ADD?  if so it's the G58

if its the W56, the case should be directly interchangeable with '89-95 cases and W56 trannies.  i'm pretty sure the forward shift rods on that version of the t-case are a bit shorter than the G52/G54 style on '84-87 carbed trucks.  only '79-83 trucks, '85-88 pickups and 4runners with EFI and turbo trucks with bucket seats got the top shift versions

[BigMike]

Well it does, but generally speaking, all 4cyl transfercases from 1979-1995 are the same.

More specifically,

• All 1979-1982 4speed transfercases are the same because they are TOP shifting, have a special 4speed input gear, and use a SHORT reduction housing design due to the cast iron transmission design (L43 if 11/1978-10/1980 or L45 if 11/1980-10/1982).
• All 1982-1983 5speed transfercases are the same because they are TOP shifting, are the first to use the 5speed input gear with the 'fuse', and use a SHORT reduction housing design due to the cast iron transmission design (L50 if 11/1981-10/1982 or L52 if 11/1982-10/1983).
• All 1984-1987 5speed carburated (22R) transfercases are the same because they too use the same input gear as the '82-83 5speeds, however now the low range gears have two extra preload plates that we refer to as "run quiets", they are FORWARD shifting, and feature a TALL reduction housing design due to the new ('84+) aluminum transmission (G52 if 11/1983-10/1984 and G54 if 11/1984-10/1987) design.
• All 1985-1988 5speed EFI (22R-E) transfercases are the same because they too use the same "run quiet" gear set as the '84-87 5speeds and the TALL reduction housing design also due to the aluminium trans ('85-88 W56 ), however they are TOP shifting.
• All 1986-1987 Turbo (22R-TE) 5speed transfercase are the same because they too use the same "run quiet" gear set as the 1984+ models except that the input has an increased spline count of 23-SPLINEs, they use the same TALL reduction housing (this time for a R151F transmission), but are FORWARD shifting.
• All 1989-1993 5speed transfercases are the same again because also use the same "run quiet" low range gear set as the 1984+ units and feature a TALL reduction housing design (this time for the late model W56), but not only is it a FORWARD shift style, but its also a SHORT-ROD version of the Forward shift rods, the rods are a bit shorter than the carburated 1984-1987 forward shift style, except the late model W56 has the transmission shift lever and the transfercase shift lever closer together in the 1989-1995 model trucks to make it more "convenient" for the driver to select between the levers.
• All 1994-1995 5speed transfercases are identical to the 1989-1995 style transfercases except they use an ELECTRIC SPEEDOMETER GEAR SPEED SENSOR as apposed to the cable type that is found from all previous transfercases from 11/1978-10/1993
• Oh, and one last thing is that, we dont know for sure, but we believe that all 1979-1980 transfercases used a mainshaft that had a softer heat treat to it since we have seen these "yield" under torque as apposed to shearing in half.

So do ya got it? 

[BigMike]

and turbo trucks with bucket seats got the top shift versions

Nope, even bucket seat Turbo's used Forward shifting rods.

i'm pretty sure the forward shift rods on that version of the t-case are a bit shorter than the G52/G54 style on '84-87 carbed trucks.

Right on the money. The two different forward shift rods are the long ones from '84-87 4cyl carb and then the shorter style ones from '89-95 4cyl EFI

I got a 95 tranny and t-case(4cyl.)

Hey if you dont need the speed sensor from it, then I'll give you $20 for it. Let me know.

[4DEES [OP]]

well see the thing is, I got that tranny and transfer case(out of a 95 4cyl)on my 84 (carbed)and I got a broken t_case(ripped a piece right off)so I wanted too know if they were all the same from89 and up.this way I wouldnt have to look for a 95 transfer, I could look for a 89-95 or what not.thanx for all the info guys. oh yeah, big mike, I would probably sell the part,if I knew what it was.lol.can you explain?

[4DEES [OP]]

its out of a 4cyl, and thats about all I know on it.love the 4LO,and tranny. is there any other way to find out what        t-case it is?

I don't recall why but my notes and the website indicates there's a difference between the 89-91 and 92-95 W56 gearboxes. One indicator is Marlin's rebuild cost is $799 for the 89-91 and $849 for the 92-95, not counting a core charge. The W56 HD option on each series also reflects a difference. Why is this so? Not the cost but what changed on the W56 in 1992?

Marlin's Transfer Case Bible reflects the Type 6B RF1A Tcase (with the electrical speedo cable drive) appeared in 1992 trucks and 4Runners. The Type 6A first appeared in the 1989 truck and 1990 4Runner.

Will a forward shifting W56 fit in a 1985 Xtra Cab without cutting the floorboard? 

[4DEES [OP]]

I dont think you would have to cut your floorboard, my truck is an 84 (single cab) and I swapped in a trany and t-case out of a 95 4cyl and I thought I was gonna have to cut my floorboard but I didnt have to at all.

[BigMike]

what changed on the W56 in 1992?

I dont know what the differences are between the two late model W56 transmissions, we will have to ask Marlin about that one..

Marlin's Transfer Case Bible reflects the Type 6B RF1A Tcase (with the electrical speedo cable drive) appeared in 1992 trucks and 4Runners.

I'm pretty sure that is wrong. To my understanding, only '94 and '95 model trucks used an electric speedometer sensor with the RF1A gear drive transfercases. I will check the microfiche tomorrow-

  Thanks for the info. Was your 84 bench seat or buckets?

  Please do because it's perplexing to me. Thanks Big Mike. 

[4DEES [OP]]

jr9162, no prob, I had a bench seat when I put in the trany/t-case, I now have bucket seats but everything worked kool when I had a bench seat. as far as the speedometer, all I did was hook up the original cabel to where the digital one goes, works good. are you planning on swapping in a newer trany/t-case also?

[jr9162]

  Great to hear. Yes, I'll use the R151F and hopefully convert to 23 splines a late model gear driven Tcase as my1st choice. 2nd choice is a W56 with Marlin's HD option and late model gear driven Tcase like you did.

So is there any thing you had to do to hook up the speedo cable to the 95 Tcase?

What bucket seats did you use? My 85 Xtra Cab has a bench too, and I may want to swap it out. Not definite, just maybe... 

What are u running for an engine?

[4DEES [OP]]

to hook up the speedo caple all I did wasconnect the original cable to the input for the digital one, it threads right in ! I got bucket seats out of an 86 extra cab (parts truck we had layin' around). as for my motor,4 banger baby! I got the  O.G. 22r carbed with 238k miles on it and an oil leak( the motor is tired ) well, I guarentee you wont regret swapping in one of those trannys& t-case.let me know how it goes dude
