There are two A230 ratio sets, that I know of; 2.55-1.49-1.00, splits of .584-.671; and 3.08-1.70-1.00, splits of .552-.588; Check out all the splits. I think the 2.55 was for V8s and the slanty got the other one, but don't quote me, Said AJ/Form. The 'close' ratio came in the 340 and 383...

follow up. Glad Dan came through. I was writing about the countershaft washers, which was the subject at hand. Plus the damage on your washers is on the countershaft side, not the case side. They were doing the job they were meant to do.

I did a little comparison. The front spacer should allow using an 833 thrust spacer. The rear does need a smaller diameter on the 230 for clearance.

Odd also with a 69 stamp, 9B..., and a Aug build date 2944. Should be 0B... !

Yes, call Brewers to check. He may save used ones from a tear down. BUT the A230 doesn't get much respect and hence stocking rebuild parts can get neglected. I do save used tear down parts from the 230, and should have them. I looked in my NP parts book, and surprisingly there isn't a PN for...

Yours would have the numbers 65 stamped onside of case. about 2" high numbers in white ink.

Yes, this can be done. I've had it done, worked fine.

ID information on this A230 subject. I looked over 2 gear sets I have and do have both ratios. Observed that the close ratio gears have a groove on teeth to distinguish difference. Tooth counts are different, but the groove is the ready reference.

the helix was different on ALL gearsets.

Well you dont want a 833 OD, imho. If Passon it is, then simply using an 18 spline disc should be main need. Plus the throw-out bearing for an 18 spline.

exactly, huge effort for zero return. and for a slant six!! even. Complete waste of time.

I have a nice used one $25 shipped.

Yes on the size 4.35" Yes on the replacement procedure

Most likely the gears were a match, hard to believe a HH gear would mesh with the later. BUT all bearings "look" fine, they are not, especially the 308 bearing in the OD. Synchros always need attention. takes eyeballs on the unit to make any more comments.

mopar56, you are confronting the issues of the OD gears. As always too many issues to deal with in a post, but did you install new bearings? The comment on different gears is correct, the 'early' gears were call HighHelix and have differing teeth counts. I have several nos HH gears. I rebuild...

Point of fact PLEASE. Who or what is 'Ram' ?

I have an idea. If by chance the rebuilder had switched out the 68 1-2 gear fork pivot to a earlier pivot ( like because of bad threads) it will interfere with the reverse lever, as it is pulled back into place. NOTICE how in 68 the reverse dog lever has a wider flare on it where it hits the...

Having an OD 4 speed trans, without having to change all the bellhousing and flywheel to the late 70's gear, has been a desire of mine for a while. I finally did it and it can be seen in the Mech parts for sale listing. I have wanted to make a custom 4 speed trans using the Overdrive gears...

The reason to remove the reverse slider shaft is to change the o-ring. Weeping oil out of the pivot can be annoying. Yes it isn't easy with out making a reverse screw press.

Hej That is a late 1970 date code, IE a 1971 build. The vin code / factory id is missing, so little else to know by the numbers.

18 spline vs 23 spline. the 1505 bearing is easy to replace onto the cast housing. to save money if you dont need the retainer

That tag is an original tag. came on 66 67 era trans. The cases in mid 67 year started casting inthe boss, as trial run for the 68 versions for the vin stamp info. Note how they made it larger in actual 68 use.

gear cases up to about 65 had the ratio stamped on bottom side of case, on a 'flat' area. not sure it would change my idea to buy the gears either way, suregrip 3.55 or 3.91. got to do it

comment number 10 is the key here, but he didnt go far enough to explain. It is the brass STOP ring which stops the freewheeling gear enough to slide the slider ring onto the gear. If it doesnt slow down enough to 'synchronize', the slider wont engage, and you hear the grinding. So the...

The 66 and 67 833's , and later OD's had 26 spline shafts, therefore a different yoke, like the 904 AT.

NOT so fast . If we are talking about the 1st gear on the SHAFT, ie the rear most gear, yes you could. Count the teeth, if it is 35 teeth, you are good to go.[ 3.09 , 2.66, OD ] all use a 35 tooth rearmost 1st gear. The counter gear differs, yes.

I will put in my 8 cents worth. This sort of leading question, always brings 10 more, that I would ask. But first off, why did you buy a B trans with the idea of putting it into an A body. Are you not aware of the fit issues ahead of time? Without seeing the trans, I assume it was a good...

The numbers are production line codes, show up on build sheet, They help identify which transmission goes in what application, since they all look alike from a distance. Here is a photo of an original stamping This being a 1970 hemi / 440 B body trans

this usually is a stop ring issue. you did put in new?

Please use correct terminology in this discussion. The STEP looks clearly machined, and I agree with idea that is was machined to fit an incorrect pilot bushing. Check dims, and reuse if clearances are correct with existing bushing / crank. Or replicate in a new crank with a new incorrect id...
