A833 ? - 01/20/14 02:44 AM
I noticed it is hard to down shift into 1st. You almost have to come to a complete stop or it is very hard going into 1st gear with a slight grind. Trans up shifts great with no noise. Also reverse can be difficult at times. I only drove the car a few times before we pulled it apart. I never had one of these apart. Any ideas?? Thanks Larry J

Sounds like the 1st gear synchro is bad. Reverse can be a LITTLE difficult at times since it is not synchronized at all, especially if oyu have let it sit in neutral awhile, the gears tumble when in neutral even with the clutch in. I will generally go to first and then directly into reverse, by ding this you stop the tranny movement and slip it into reverse before it starts back up.
For what it is worth the are not hard to build and it only requires a few "special" tools nothing serious.

?????????? How often would you downshift to 1st without coming to almost a complete stop ?!?!?!? The only time I can see downshifting to first would be for a street corner and then you should be slow enough to downshift. If not then you shouldn't be thinking about first !!!

I don't downshift to 1st a lot but still needs to be addressed. Its out why not fix it? Thanks Larry J

I experienced the same thing and found it to be a combination of synthetic gear lube and rounded off dog teeth on first gear.
Switching to regular gear lube helped a bit.
Grinding is typically from the gear still spinning, which means the stop ring (syncro) is not keeping it from spinning. This could be from the synthetic lube or that it's just worn out.

Is this something I should try to fix or off to trans shop?? Thanks Larry J

I would try changing the gear lube first, it's a minimal investment.
If that doesn't fix it, it needs dissasembled. Ship it to

There easy enough to build, I've never done anything that I didn't do a first time.

Is there a rebuild manual for A833's? Not sure I would just start ripping into a trans without some guidance. Thanks Larry J

I live in North Florida and frequent the Philly area if you are within 100 miles of either I'll come walk you through it.
IDing good vs. bad parts is pretty straight forward at worst you can post pictures and we can help ID good vs bad. I learned to build manuals at 16 so it aint that hard. I have only had 1 in 30 years I had to go back into and it was after 8-9 months of hard use. Seems the clearance between the 2-3 gears/synchro on a T-150 is an known issue I didn't know about.

Replace what's cheap or looks bad. All seals and gaskets. Front bearings have a tendency to go but the rears usually hang in there. Bottom and top rollers seldom need replacing but looking at them will tell you. Thrust washers should be replaced. Shift forks likely need replacement. Syncro rings should be replaced. That's pretty much the standard, inexpensive stuff. Now comes the expensive stuff.
Ideally the teeth on the syncros should be sharp HOWEVER, its highly unlikely they still are. This doesn't mean they're junk or won't work. New syncro rings usually solve most issues.
I'd say if you do all that yourself and use the proper lube you'll have a 95% chance its as good as new.
You only need one special tool - external snap ring pliers. I bought mine at Sears back in the '70's.
To remove bearings from the shafts: one thick chunk of wood (preferably a hardwood) on the floor. Hold shaft with bearing towards the floor. Drop shaft assembly from a one foot height repeatedly until the bearing falls off. Works for the front bearing too.
For the tailstock bushing and seal, take the tailstock and parts to a tranny shop and they'll usually do that for coffee money.

Any grind in Rev is not normal. Input shaft is still turning. My $$ is on the following:
-Pilot bushing tight
-Bellhousing out of alignment
-Clutch not adjusted correctly

No grind in reverse just hard to shift into reverse at times. But a slight grind into first always unless you are almost stopped. Thanks larry J

I usually double clutch into first, the first gear synchro wears out fast in most trannys
