HOW TO DO AN ADVANCED SEARCH.

Mon Jul 08, 2013 3:56 pm by Admin


For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.

When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

will a 86 944 S transmission fit a NA 83 044

Post  Vorsche944 on Wed Nov 18, 2009 6:53 pm

HI guys,

tired of looking all over the net and decided to ask the experts. I am selling my 86 944 5 speed transmission to a guy who has an 83 944. Will this fit his car? Or what questions do I need to have answered to make sure.

Your help is appreciated.

It is very likely that it will just bolt in. All of the old style bosses/threaded holes should be there. Although some cases may need the holes drilled and tapped. There are three bosses on the drivers side (opposite side of the diff cover) and there are two studs that hold the diff cover on that are used along with one on a boss just below the top center stud. This is where the mount brackets attach. The pictures of the turbo transaxle show the holes on the drivers side and the untapped boss on the diff cover.

I don't think I have seen a case without the bosses.

I think James (RobotMachines) had to modify the mounts...

Ive had an early (pre-85.5) tranny in my car and it bolted up just fine. The speedo sensor had to be swapped from my late tranny over to the early one but thats easy. Not sure if this helps but the integral mounting of the cases themselves are all the same.

See the hole on the bracket on the diff cover that doesn't have a boss? That is the boss that may not be there. The ones on the other side should be there.

The 944S officially went on sale in August 1986, so it is possible some were titled as 1986 model year.

Here are some transmission #;s that might help. It may just be a 86 NA.

87 turbo tranny in 83 N/A

Post  map21 on Mon May 09, 2011 6:51 am

Sorry to revive a very old thread but I wasn't really able to get a clear answer based off my research and what has been posted here.

I just purchased my 87 Turbo Transmission. It is a UY code box with no cooler or LSD. I have an Audi V8 Torsen Diff at the house waiting on this tranny and of course my current N/A 5th gear also to incorporate. Planning all the mods at one time for simplicity. I am aware the turbo box will bolt to the TT and physically fit under the car just fine.

The question is since my car is an 83 with early tranny mounts and the non removable transmission hanger bracket. Will my 87 turbo box bolt directly up to the upper middle mount using the early mounts?

The second question is about the modified mounts that are in gt1scca's pictures from James (RobotMachines). For one I have no clue what part that is since I'm no where near my car. 2 is it necessary or was that just a mod to save money or avoid buying a new whatever that thing is.

Lastly this talk of missing boss's. Would that be on the diff cover i.e. just purchase the right diff cover or swap it out or is this on the actual transmission housing. pointing it out on a pic would really help.

I hope I'm not being to much of a newbie with these questions but I really could use some guidance on this. Thanks Matt

From what i have seen, the diff cover may or may not have the boss. If it does not have the boss you could use the cover from your old transaxle easily since you are adding the new diff as well. The cover from the old transaxle alone would likely need some adjustment to just bolt onto the turbo transaxle as the bearing pre-load would most likely be different. (adjusted with shims on the diff side bearings) But since you are going to replace the diff anyway now would be a good time to swap covers.

Then you should have all of the holes necessary to use the early mounts.

Easiest way is the bracket mod as seen above......It actually is stronger that way.

Well I thought I was the only one trying to use a 86' Turbo 5-spd in a 84' 944 that had an automatic.

I just recieved a pair of the early meatal transmission plates and started a mock to see where the plates bolted to. The drivers (left) side of the trans is good to go for the three bolt holes. The passenger (right) side has only two holes to bolt to after removing the two bolts from the diff cover and as on my trans case there is NO boss (bottom right bolt hole in metal mount plate) to drill and tap. I didn't know about being able to change the diff cover. Not sure my automatic diff cover will work but I will check it later for an option.

Thanks for the pictures on the modded metal mount plate as I was thinking about trying to use the 86' top mount in conjunction with the early mount plate so now I know. cheers

Here is some more info on the elusive missing mount boss from the newer tranny vs. the older tranny. The tranny in the foreground is from a 86' turbo 5-spd and on the diff cover I removed the two bolts where the metal mount plate would bolt up. Below the hole on the right is where the stated missing boss would be or was located.

The tranny in the background is a QM early 5-spd where I removed the two bolts from the diff cover and the third mounting hole under the right bolt hole in the diff cover. If your tranny has the boss in place but not drilled and tapped, fantastic. If there is no material boss then follow previous suggestion in the thread by modifying the motor mount, easiest and quickest mod IMO, or change out the diff covers (I have no idea as to what this would entail).

Parts needed to go from 85.5' newer into the older 944's is the 2 piece-early style metal trans mount plates (manual trans, as pictured ealrier in thread. auto trans are different) and the two rubber mounts (same in both early auto or manual trans) that bolt up to the body crossmember or contact xschop for a pair of his billet polyurethane mounts in place of the rubber mounts for a more solid mount up to the crossmember.

I was thinking of changing out the gear set from the turbo tranny to the early tranny housing and keeping the early N/A 5th gear but it looks far simpler to just swap out the 5th gear to the turbo tranny and mod the metal tranny mount. I am having enough headaches swapping out the auto-trans for the manual as it is. Just gotta love conversions.

It would be a big undertaking to swap the 951 ring and pinion into the early transaxle. There are many big differences. The front pinion bearing is larger in the 951 so you need to bore the case. the ring gear is about 1/8" larger in diameter so the case needs clearancing. The main shaft and pinion shaft are longer so a case spacer needs to be made to go between the main case and the gear case. These are the big things.

If you had an S or S2 the ring and pinion would just swap. But if you just wanted the extra boss it would be much easier just to swap the diff covers.

I was looking at those pics yesterday and you could also build a trick bracket out of angle iron or square tube that spans the early mounts and interfaces with the Late trans Intermediate bracket. Hell, I wish mine were like that and would be even easier to remove the trans.

Couldn't you just bolt the square tube to the original early mount holes? I would close the tube ends and weld a couple of pieces of smaller tubing through the square tube for the bolts to go through so you wouldn't squeeze the square tube.

Yeah, but it would be loud cause then it would be solid mounted. Tehone has my billet-poly mounts and I'm sure it wouldn't be a straight bar shape, but more of an slight ox-yoke shape. Depends on where the trans hangs.
