Please tell me its something besides the sprag backwards, no movement in drive it has reverse it has man 1 and 2. Is there anything else it could be? Has good line pressure.
Just cant believe i did this.

 

What happens when it shifts into 3rd?

 

I didnt try to drive it its still on rack.

 

Did you use Sonnax pinless on Forward acum?

 

if it drives in 1 & 2...it is not the fwd accum. I'm not sure why you have such a hard on for that accumulator lol

input sprag is the issue here.

If you were to drive it, you would be able to start in 1st, shift to 2nd, then shift to 3rd at an appropriate speed...and when you shifted to 4th it would either lock up, or break something.

 

Yes i did use a sonnax forward accum

 

thanks these transmissions are not for faint of heart just glad its 2wd

 

Are you sure you beat the 2 checkballs inside where the pin should go?
Im asking that for a reason. I had a deal with it and i had the very same symptoms.
Because if you did put the 2 checkballs in the bore, Maroon is right. And if Maroon is right, then it's a really really bad news for you....And Maroon is 99.9% Right. Im just leaving that 0.01% for mistake that i did before, that Maroon would never even think of because it's so stupid to miss this step.

 

i didnt see where putting the 2 checkballs in would do anything so no i didnt.

 

omg dude that fixed it!!!!
thank you!

 

somebody isn't telling the whole truth here.
The initial post says "Has good line pressure."

if you did not install the accumulator correctly and had a huge hydraulic leak...then you would NOT have good line pressure

besides...it is the FWD accumulator...you'd have that huge leak in ANY forward gear...including manual 1 and 2
the story here does not add up

 

In Manual 1 and 2 your fwd clutches wont engage with that leak. He ran on overrun clutches only in manual 1 and 2. He wont be able to shift to 3rd gear anyways, only on high speed.

 

The overrun clutches only take the place of the forward sprag in manual 1 and 2. You still need the forward clutch pack to move forward.

 

Then what kind of magic power driving the vehicle in D1 and D2 with that huge fwd leak? If you state that im that wrong, then give your explanation to this mystic phenomen.

Im no expert, but my guess is the leak partially apply the right pressure for 1 and 2 this way :

When you put a sonnax pinless, it completely blocks the fwd acum bore from outside. And this is the only leak path that exists


So maybe the line pressure is enough to run 1st and 2nd and 3rd(only on high rev).

I didnt check the line pressures tho, but i can clearly state that the tranny runs like normal up to 2nd gear.

 

No huge forward leak. Op says in post 1 "Has good line pressure". As said before the facts have been mixed up.

 

Then we dont know something about this tranny.

Btw, the creator of this post could just assume the line pressure is good by judging how it runs on Reverse, D1 and D2. It runs like normal

 

Please forgive me, I checked the line pressure in park, I honestly dont know why i said that as im lucky that edward must have missed that part. everything was going wrong at that time and panick had set in. I took the gauge off because it was leaking. sorry for the confusion, maroon ive read alot of your post and ive learned alot from you and alot of these other guys on this forum.

 

listen, if you're saying that the pump can apply the overruns despite a .250" hole in the fwd circuit
fine by me

Is it possible for the overruns to move the car without the fwd engaged? yep

is it possible to engage the overruns with that much leak in the fwd circuit...I doubt it...but I've never been in a situation to test that theory just for fun...so if you're saying so...I guess I don't care enough to argue.

I have a bad feeling this thread will result in a poor bastard in the future with a forward sprag issue who will waste his time chasing this fwd accum leak for no good reason.

 

for the record the tires never hit the ground. I just felt it engage in manual l, engage in 2, and reverse. Look it could have been slipping like hell but all this happened in less than a minutes time. Done had alot of money tied up in it didnt want to take any chances.

 

......I feel we have two accounts and one person here.
