So was curious, not like i have any money for this now, but how strong and how low of gearing can one make a type 1 irs tranny. i know the reverse gears suck ass in stock ones(blown a few when stuck in a mud hole). just kinda wondering if it would be worth it $$ wise or not, i know go to a bus tranny. I would like to, but have read so many bads and goods about them fitting right and linkage problems. if i did i would want the shift rod in the tunnel, but then doing the 10* kit would raise it up causing more angle on the cv's. Was just thinking if i could get a type 1 beefed up well enough and put 930 cv's on it i could get my clearance, and retain the stock setup. I've read lots of posts on bus tranny's and such, just wanted to see what everyone thinks. lets here your opinions.

being I got 2 hours out of mine on my last trip..... and spent six hours taking it back out... I suppose I have some what of a biased opinion at this point....

One more opinion, on the bus trans... with the shifter linkage above the tunnel, you have the option of moving the shifter box back, closer to the seat making it easier to reach.... which is nice if you have shoulder harnesses

I was wondering if you could move the shifter further back, just for that reason.

why not just do a bus trans with 930's and the 10* kit? Sure the 10* will cause more CV angle, but thats what the 930's are for.

the 002 uses the same reverse gear as the typ1.

Actually the 091 and mendeola 2e and 2d use the same gear too.Ever see why so many buggy owners break reverse with the Ls1 motors and subies just backing into the trailer.

if i ran my shifter over the tunnel then no ebrake.

If driven properly you can get a lot of miles and use out of a stock tranny.

I have a super diff (circa 80's) couple welded gears, type 2 cv's and was told a 70's ghias tranny (has some lower gear ratios i was told) and have busted it twice. first time was when i dropped the clutch too fast with 3 people in the car and kind of in a ditch and new beefy tires...after my "lesson" i went for years and many off road mile without ever having a problem ..including a fair amount of being stuck and messing with forward reverse shifts and steering brake manuevers.. well then when i rebuilt the car my son went and tried to lay a burnout on asphalt pavement...big engine, new tires, rev up ,drop clutch and "busted"..

I agree with this, i have a well built type 1 trans, super diff, 4.57 r&p, steel forks,hardened keys. When I put the 3x3 kit on with 930's the shop i got the kit from told me that with that travel and the fuel injected 2110, my trans wouldn't last 1 season. That was 6 years ago. I drive the car hard but I don't abuse it. I don't drop the clutch on pavement and when the car is airborn I let off the gas. When I do finally have a failure, i will have it rebuilt and go from there. I have seen planty of blown up 002's and 091's for sale. If you don't abuse your stuff it will last if built right.

Ghia transmissions have the same gears as a Bug. Until you get to about 1972. Then, they got the 3.88 R&P first.
Also, the later IRS transmissions have a finer tooth gear on the 3rd and 4th. This was done to quiet the trans down at highway speeds. This also weakened the trans for offroad use. But then how many offroaders actually ever get into 3rd or 4th gear.

A lot of us live in those gears actually.

Just to give some more insight on the subject. Class 9 cars pretty much have to have the tranny rebuilt every 500 miles at least. These are Type 1 swing axles and do have plenty of upgrades in them.

Isn't the only VW manual transaxle that has a bigger reverse gear (than the T1) the 094 side shift?

I believe thats right. The 094 "mid-shift" as its called does have a stronger reverse. I found one at a local junk yard and was tempted to get it until i learned that a different shifter would be needed, and i would also have to get a $500 shifter cable mechanism.

We used to be sat on the rev limiter in 4th quite often :wink:

my brother has a type 1 trans in a rail with a 2276 and stands the front up in the air all the time. still on 1st trans. iv heard that a type 1 with welded gears and a superdiff was just as strong as a bus. seeing my brothers run i belive it

mmmmkay...
so.. I have at least I.D.'d the spot that my drivetrain has the weak spot...again

How much different is the ring and pinion?

I'd like to rebuild one with a rhino case, but waiting for a deal.

In my opinion, I think type 1 trannys are plenty strong. I race class 11(full body bug) in the desert and I don't think you can put any more stress or demand on the tranny or car for that matter. The rules are limited too. VW type 1 trans, stock VW gear ratios, VW 4.12 r & p. the only mods allowable are welded 3rd and 4th and super diff. I also use German type 1 cv's, which I polish and massage begore putting into use and have never had an issue with eiterh when properly manintained. Although, I can run type 2 cv's, I haven't made the swap yet because I would need to reset up the whole rear end of the car's geometry for travel. As far as reverse goes, it is weak in any VW configured tranny-PERIOD! The only thing reverse is for is backing the care off the trailer or out of the garage. If you have to use reverse to get out of a situation, and I have, the only word of caution is, firmly hold the gear shift in reverse and let the clutch out easily. If you rev the piss out of the motor and dump the clutch, I can almost garantee they you will be rebuilding the tranny, while on the subject of strength, another item that I don't think gets enough credit is the ball joint front end. Again, in my opinion, the ball joint is plenty strong for off road. The ball joint itself being the weak link, we change them out once a year, 6 to 8 races.

I'm not sure one that, we blew 3 to pieces even with a mildly sorted 2.1, they lasted perhaps 2 events at best, sounds like he's doing a bit of mudwork and they really don't like that...

Sun Jan 10, 2010 12:16 pm

is there heavy duty or strengthed reverse gears for the type 1?
