Swap 4-speed for 5-speed?
« on: Sep 30, 2007, 07:08:10 AM »
Can I put a later model 5-speed in my 82 4x4? If so which years will fit and are there any modifications that will need to happen or can it just be bolted up? thanks

The 5 speed is longer, that will move the t-case support bracket further back. Just have to fab a new one or buy one. Either way there will be welding.

I'm cool with the welding and as long as I can buy the bracket I think it's worth it. Do you think it will really benefit me in the long run?

Yes, you will get a lower 1st gear & an overdrive gear. Do you know what transmission your getting. Here is a link that will give you some spec's.

the easiest  for you would be a  L52 5 speed,  they  are in the 83 models  and will bolt right up  no mods at all


the  G52 or G54  and W56  will have to have the tcase crossmember moved back

but will all bolt to the engine with no problems  you will need to get the clutch fork  and throwout bearing for the tranny you get

I am doing this swap to from a 43 to L52 I was told that you had to grind down one of the shafts so you transfercase would fit?

:smack:  yes  the input  on tcases found behind the L43  dont have the "fuse"  like the later  tcases have,  so  you must remove a small amount of the spline

i'll try and fine  a pic for ya,  it can be done with a angle grinder  with the tcase in one piece  if you cover the  tcase bearings with a rag or something


ok heres a pic  of  a input shaft  with a  "fuse"  note  the  splines  drop  to a smooch "thinner" area befor the  seal area

i couldnt find the pic of the L43  but the new total splins is similiar  it just doesnt have the "swell"  the L43  input does 

note the area i circled,  this is the area  ONLY OF THE SPLINES, that needs to be ground off

pull the coupler  off the L5# tranny  so you can see how far it goes on the input,   when you do that  and with the instructions here  you will see what has to be done  :thumbs:

Finally done with this and it is running great.  I only have one question.  My reverse lights are on all of the time now they won't go out.  There is a switch that I can't find where it goes to.  This isn't a huge deal just seeing if there is a simple fix.  Thanks

I thought that 82's only came with the (L45 4 speed or L50 5 speed)?  :dunno:

best mod I have done to my 80 p/u , I bought a t/case from a 83 instead of grinding down the splines , whole job took me about 3 hours from start to finish , make sure you have help putting the L52 in , it is a heavy sob

thanks for your post. I was trying to think of a way to get around grinding the splines myself. Did the 83 t/case mount right up?

I've thought of doing that myself.  I have a spare case off an 80 for mine, but in all honesty I'd rather not have to do any grinding to fit it.  That said, I could always just change my forward shift 4.7 case to a top shift and run it, but I'd rather wait to do that until I have an adapter to run duals.

I have an 83 tcase I am gonna be pulling off my L52 and putting my stock tcase from my L50 back on.  Seems as tho it screwed my gear ratio up and it chatters like hell in 1st and 2nd.  Starting to think someone messed with the ratio in the tcase because it runs bout 120 rpm less at 75 mph then it did with old tcase. 
If I do swap it over someone is more then welcome to it if ya live in concord ,ca
The swap to a W56A or B imo is the best swap to do. Mainly due to the W56 A and B are top shifters like the L50 series and the output  bearing is MUCH stronger.  Really taking drive shafts in and having the front one lengthen and rear shorten is a good thing as well.   I plan I doing this swap over here pretty soon.  Need my Hy steer 1st. No power steering sucks!!!  :idea:

I ran the 4 speed for a long time in my 79 and I liked it alot. But once I put the 5 speed in, it was like a whole new rig. Way better with the 5 speed, and I think I get better MPG.

I swapped my L43 4 speed for a L52 5 speed-it was a complete bolt in swap; no floor mods, no "spline grindin" the dual case set up all works w/ no problems, no driveshaft work was needed..just needed a different slave cylinder which yours truly(Marlin) sells :twocents:

I went from an L50 in my 81 to a G52 from my 87 carbed truck.  I used the slave cyclinder off the G52 and kept the transfer case that was with the G52(forward shifting).  It is about 3 inches longer so I did have to modify my crossmember.  All I did was turn it around(front facing back) and it bolted to the back holes of the original crossmember mounts.  I had to use the tranny mount off the 81 and put it facing forward like normal. I had to enlarge the tranny mount bolt holes in the crossmember to slide the mount as far back as possible to keep it from binding.  Then I welded on some angle iron to the inside of the frame rail and put in 1/2" bolts.  It only has 3 bolts per side now but it has held up just fine.  The back up harness matched up but my 4x4 light harness didn't on the transfer case.  The shifters lined up perfectly but I did have to drill some holes to get the shifter bolts tightened up on top of the tranny and transfer.  I also used the shifter boot off the 87.
