Hello just finish putting in 351c 2v into a 73 mustang. The engine came from a 73 ranchero, the mustang has a FMX tranny. I don't know the history of the tranny.
When I started the motor and place the tranny in reverse the vehicle moved forward and when I placed the tranny in drive the vehicle moves backwards. Any
Any idea what would cause this problem?
What do your other gears do?? I'm thinking your arm is upside down, compared to the old tranny. What is the rest of the pattern?
Don
The selection pattern is the same except for r is drive then neutral then d is reverse.
Do I have to pull the tranny to flip the lever or can I just drop the pan and do it?
I don't know about your tranny, but on a turbo 350 the arm is held on by an external nut. There is a 'double D" shaped spline that lets you flip the arm over and put it back on reversed, then just retighten the nut.
I'll bet that the donor car had a column mounted automatic shifter. Either that, or someone installed a reverse valve body into the donor transmission.

Your driveshaft is installed backwards...
Lucky you didn't do that obligatory "break in" holeshot

Don
:whacked: yes that would do it **) the tran.s lever needs to be flip like saidQuote:

So the pattern goes PRND21, R= D and D=R, neutral is still neutral.
You probably got your lever upside down.
If the lever is upside down or backwards....wouldn't P=L1 ?
If neutral is still neutral, then I dont see how it could be the lever. Seems as though a backwards lever (if you could get the linkage to accomodate) would put neutral in the drive position as seen on the gear position indicator.

Could be the driveshaft too like Gusaroo said... ??
Or the axle is installed upside down....
Wasn't there a string issue about this a while back? A guy flipped his axle over when moving it from below the leafs to above (so he didn't have to re-weld spring perches...)
Wasnt there a Seinfeld episode about the Bizarro world
where left was right, up was down, and reverse was drive?

Thank you for posting this.
Exactly what I was trying to clarify with him. Need to know, when you put it in normal Park what do you get, when you put it in neutral, what do you get, when you put it in 1 and 2 what do you get ? All you have told us us what D and R are............not enough info.
Don
He said it upshifts in reverse... NOT a lever problem.
Diff is flipped over.
Damn... I was just kidding about the driveshaft and flipped axle... :whacked:
How in the hell could that have happened?
:confused: :confused: :HMMM:
Okay, Wifes65, did you get this sorted out, yet?? Inquiring minds want to know. :rolleyes: **) :D

Some guy I knew thought it would rake his '50 Ford if he flipped the rear over so the spring perches were on top of the axle. He got it all buttoned up, put it in reverse to back down the driveway, and it went forward. All of us fell on the ground howling.:LOL: :LOL: :LOL:
But, I don't see that happening here. He didn't say he removed the rear axle, just the tranny. What I want to know is WHAT HAPPENS IN EACH GEAR, NOT JUST D AND R.
Come on guy, we want to know what happened.:confused: :confused: :confused:
Don
yup, I had a buddy do the same thing when swapping the axles from under to over the leafs to lift his jeep...
First car i ever had was a model A. Had to fix a broken axle and replaced the ring gear and axles from the wrong side. Yep, you guessed it! 1 speed forward and 3 speeds in reverse. Same principle applys today. (I think)
Doncha just hate it when they get you thinking about some problem and never post back what they found??? :D :D :D
Come on guy, tell us what's going on.:3dSMILE: :3dSMILE:
Don
Could it be the axle is fine but the world has turned on it's axis?
No, problee' not, then we'd ALL be goin' backwards. Then again, better check just to be sure. **)
man ... havent posted much lately...pretty much been a lurker... (hic)..
but yeah this one has sparked an intrest on the results........ we wanna know...
Ain't that the truth, Pro? Some days, well, actually, a lot of them, I feel as if I am going backwards, or at least downwards. :CRY: :whacked: **) ;)Quote:
---- then we'd ALL be goin' backwards. Then again, better check just to be sure.
So, I wonder where ol' "wifes65" got off to. :confused: :rolleyes: Prolly got that thing in reverse, and drove off into the sunrise. :eek: :LOL: :LOL:
would be a nice custom though...
rearrange the interiour from back to front and get used to rear wheel steering and your off!!
sure will catch some strange looks, going down mainstreet!!
how to make a rwd a one of a kind fwd!!
