Isuzu to Getrag
Tuesday, September 12, 2006 12:03 AM
Ok I've searched and I've asked questions. But I keep gettin different answers. My isuzu is about done and I want to put in a tranny. Some people say you need all this stuff from the getrag and others are like you only need to weld the rear mount and hook up cables. I would like to know from someone who has did it, what exactly is needed to put the getrag in a 99- Z.

Maybe this is a reason for your confusion:

What getrag are you talking about.

there is a how-to posted here in this forum.... use the search.

cut rear mount out, weld in new, trim/drill the front mount, swap cables/shifter/clutch hydrolics........ Ian Brydon found out that the 95-99 clutch/flywheel wont work with the 00+ getrag, so your going to have to swap that as well (which is wierd, cause the 95-99 setup works on the older NVG, which uses the same setup as the 00+)

Well do you have a link to it because I searched in this (transmission forum) and didnt find a how to on the getrag. I searched under getrag swap then just getrag and found nothing. With a swap how to just the same stuff I've been finding. Some say you need the axles and stuff some say it bolts right in w/ the rear mount relocated. This is my daily and I have a four day weekend coming up next month that I want to do it in. Thats why I'm asking for a how to so I can get everything together and just do it.

looks like your right, I havnt found anything on the swap either....... just a few of the posts where I entered some of the info......

What info do you need? I've done 2 auto - Getrag swaps, and one Isuzu - Getrag swap (if your talking 00+ getrag)

Axles, same
Clutch Hydrolics, different
Cables & shifter, different
mounts, different
mount brackets, different
mount inserts (prothane), same
Clutch & flywheel, different

Ok basically I need to know what I need to buy besides the tranny. I have tranny and clutch I thought I could use the same flywheel. And by shifter you mean the actual shifter itself or do I need everything except axles.

is there a reason why you use the new getrag instead of the old getrag that just bolts right up without all the cutting and welding??

Wait really I never heard that one before I knew you could use the old getrag but I didnt know it required less modding. Whats the difference in the two. And for the F23 what all do I need someone here whos done the swap has to have something. I wouldnt mind just tearing into it and finding out as I go(the best way anyway) but this is my daily and I dont have time to do that I have a four day window. But, whats the difference in the two and how could I find an old getrag that has low mileage on it?
Re: Isuzu to Getrag

Sorri guys I mean like part numbers and exactly what hoses and linkage, b/c the tranny I found only has the tranny no linkage or anything. So I have no idea where to get the other stuff I need. Or exactly what the other stuff is.

dude you really need to read some of the other posts on this page...it takes very little modding to install and you can find it off any quadHO equipped car from 93-94..and SOME 92's ..just make sure it comes with TWO tranny mounts and not one or you dont want it




Re: Isuzu to Getrag

Why would that be bad if it fits into the factory mounts and what car has only tranny mount?
Re: Isuzu to Getrag
Saturday, September 16, 2006 10:30 PM
history lesson...
the original quadHO motor had differnt mounts than the Jbody...it didnt have the upper engine mount at all..
it had something like the lower one..it had a mount on the lower front of the block and it had ONE tranny mount..
the Jbody has an upper and lower engine mount on the side but no front mount..so guess what happens if you put a tranny in your bay that doesnt have a front mount...thats right..you get some reallyyyy bad engine turn and alot of stress on a mount that it cant handle
the 89-92 getrag had only ONE mount that means there is no place to bolt up any other kind of mount to it...where as the 93-94 all had TWO mounts ..both in the same location as the isuzu...only the upper/rear one was slightly differnt..thats why you need to use your upper isuzu mount with the getrag...
hope that explained it better

both transmissions work out pretty well...... the NVG needs some modding to get the shift cables to work right, and you need one of the donor car's trans mounts.... I foget which one....

Getrag F23-M86 Cavalier/Sunfire 2.4/2.2/2200
1st - 3.58
2nd - 2.02
3rd - 1.35
4th - 0.98
5th - 0.69
FDR - 3.94

92-94 Getrag/NVG-T550
1st - 3.50
2nd - 2.19 (or 2.05???)

This is awesome. What type of modding like cutting and welding or like extending stuff or what. And Im not knowledgeable at all when it comes to gear ratios and such. And this looks like a good chance to get some. So could you explain those number up top and how they relate to the speed of the car at certain rpms. Like I read once on the quad forum, where this guy took out the nvg and put in the isuzu b/c he was saying the nvg kept making making him hit his rev limit.
Re: Isuzu to Getrag

ok..the only real MOD youll have to do to make it fit is ONE of the shifter cables...one will fit perfect,the other needs to be extended by about 1.5"s all you need is a small piece of metal and drill two holes in it(something like that) ill link the pic of mine tonight ok..
and why in gods name you would take out a getrag and put in an isuzu is beyond me...what he probably meant was he was hitting his revlimiter faster(which is true)because of the gear ratios..but think about it..the faster you get to those higher rpms(which is where your power is) the faster your gonna go...he was probably lazy and didnt like shifting as much when accelerating..my best advice is -
get the nvg,get the team green lsd insert for it.. and throw in a stage 2 or higher clutch with a light flywheel while you have it out..youll rev faster than ever before and youll never look back

Yeah the pix will be great. I wont be able to get to a junk yard to look for one till next weekend. But does anyone have one in good condition.

Another bad thing about swapping to the NVG..... replacement parts are hard to come by..... Tom (WrenchMonkey) is having a hard time finding the Input shaft Bearing/Seal to replace his leaky one..... it is a discontinued part from GM.

weird...i just got one from work(pontiac)....i had to order it from Lansing ....China( i say that cus it takes so long to ship )
but seriously the computer said they had like 200 some odd units in storage...maybe i should supply the nvg world with shaft seals mwuahahha
oh and sorry bout the pics man i have them all taken..i have th bracket and the mount mod..basically everything needed to be done to make it fit right i have a pic of ....ON MY PHONE...my damn card reader is broken so i cant get the pics to the pc tonight..ill pic up a new one tomarow



Re: Isuzu to Getrag
Tuesday, September 19, 2006 6:24 PM
ok guys here ya go...i cover this so much i was thinking about making a how to...but no time right now for that..so heres the pics of the only mods you need to make the older getrag work on the twin cam..
first off youll keep your stock shifter cables installed..and keep the linkage on the getrag tranny the way it is...one cable will reach hook up just like stock..the other falls abit short so youll need to make one of these to make it fit...its about an 1 1/4" - 1.5" from hole to hole but it would work well if you simply measure on yours to make up for differnces in installs..all i did was take some metal laying around and drill the holes..not to hard huh



next you will need to take the upper/rear tranny mount that comes with the getrag and throw it out...youll need to use the mount that came off your isuzu for this...you wont need to modify it in any way just make up for lost space...you can use washers,spacers, nuts..whatever you like as long as its strong and stacks up well..ive done this a few times and get lazy with parts but heres how MINE looks at the moment



that was the rear most bolt..the forward bolt matches up flush...and the one on the side needs alittle more..the space from the mount to the tranny housing must be filled when you bolt the mount on but heres mine




and last ..you want to keep the front mount that comes with the older getrag and throw the isuzu one out..itll will look something like this



well there ya go..thats all the pics i got for now..hope that helps and shows how simple it is to make this fit over the other option..any questions or comments are welcome!



Re: Isuzu to Getrag
Tuesday, September 19, 2006 7:56 PM
Yeah this is really close to a how to. Actually what more could you say to make it a how to......Nothing! OK now to go hunt down an old getrag. Is there a certain year to look for and b/c the tranny is so old and I would have to get a used one unless someone know somewhere to get them new or close to new how hard wouldit be to find parts for a rebuild, since people say that parts are hard to find.

Re: Isuzu to Getrag
Tuesday, September 19, 2006 8:58 PM
you can still get them new from GM...but even at my employee price they are over 2g's...
the years you are looking for are 93-94..you can even use the 92 IF it has 2 mounts...that smaller front mount in the second pic..the older getrags(89-91) had only ONE mount..there isnt even a place to bolt another one...and they had an external slave (which isnt the biggest problem) but you NEED both mounts or you might have your engine brake a mount and itll fall outta the bay..hows that sound? hehe
so to keep things safe look for 93-94 5 speed getrags from HO equipped cars...lowest milage is a plus....and dont forget, team green makes an lsd insert for these trannys which i also did a how to on hehe



Re: Isuzu to Getrag

hey do you have a picture and a part number for the input shaft bearing/seal....



Re: Isuzu to Getrag
Wednesday, September 20, 2006 8:45 PM
lol i cant get it ....
i only have a pic of one installed but i can get the part number for you
