A Block On My Transmission ???

[Anonymous]

Okay, on Saturday night me and some buddies welded a glasspack on my '67 stang. (its sounds really deep, not too loud though) okay, off topic there. well okay, the question is .. they said that my transmission ha s some kinda block on it that doesn't allow me to get into gear after revving the engine .. (like, i put it in neutral push the pedal down, pull the shifter down to 'Drive (3)' and it does nothing until the the engine stopps the revving, then it goes into gear) one of my buddies said that ford made that feature to prevent "drag racers" of the 60's or something like that. I was wondering if this is true? and if it is true .. is there anyway to take this block off? (and, for some reason, wen i press the pedal all the way down, it doesn't like have torque at all, it kinda just moves up in speed gradually)

-thanks

HI
Well Ive never heard of anything like that (not being able to put it in gear when reving)? Did you witness it or just going by there hear say?
As far as no TQ when taking off your car is only a 6cyl with a automatic (not known for power or quick takeoffs) and the motor may be purty tired and not have much tq to begain with. Also if the muffler has to big of a hole through it you may lose alot of low end TQ I beleve you need some back prusher for low end TQ.
I'm sure someone with more knowage well chime in.

Well that's what they told me, so I tried it ..putting the car in neutral, stepping on teh gas, moving the shifter to drive and it just continues to be in neutral .. then wen i left off the pedal and it returns to idle, then the gear pops in

I don't know everything about fords and that is a little before my time, but I have never seen anything like that on a trans, what I have seen is a problem similar to that caused by fluid starvation. I think you may have a trans problem.......

Never heard of any such "lock", nor have I ever run across one in the 30 odd years of owning Ford vehicles with just about every automatic they ever made.

If he doesn't have one now, he will have, he will have.

LOL yeah I was pretty sure about that also, but didn't want to say 100% for sure.

Man you defiantly want to have this looked at before it gets any worse unless you have a spare tranny sitting there.....

Some of the modern manual transmissions will not allow you to downshift into 1st gear if your RPMs are too high...but that's really the only interlock I know about. THough my Volvo will not shift into reverse if you are going above 10MPH and I don't just me it locks the selector, but even if you bypass the lock on the gear selector, the ECU will not engage reverse until you get below 10MPH.

so will there be any way to have this fixed? and also, what do ya'll think is "about" the price if i were to get a new tranny? (or have my rebuilt?) .. 67 200ci

Your friend is just refering to the fact that the trans will not go into gear when the engine is reving or if you are in reverse and driving then slam it into drive it will just keep going in reverse. It isn't necessarily a lock but it keeps the trans from blowing apart when you are going down the road and accidentally put it into reverse, it will just makes a loud buzzing noise that doesn't sound healthy and keep going forward though you put into reverse. Just nature of the design and perfectly normal. NEVER PUT AN AUTO TRANS INTO DRIVE WHILE REVING OR SHIFT BETWEEN DRIVE AND REVERSE WHILE MOVING IT UNLESS YOU WANT TO BLOW IT UP.

sounds like something that could happen if the tranny fluid is too low...ive had it a few times when it was leaking that i would drive andit wouldnt shift for me but all i would have to do is release the gas and it would kick in at the lower RPMS....

YOUR ENGINE DOESNT STOP REVING UNLESS IT IS OFF...so unless its set at a lower RPM then i dont get how it would shift when the engine stops reving...but if u mean that it shifts when u take your foot off the gas then thats not too big of a deal...it'll probably sound like your a standard then 8) I've shifted like that a few times cause its kinda different....that was with my last tranny though and it didnt shift totally smooth...i should try it with his one...although i do shift most of the time manually i dont take my foot off the gas....I did accidentally throw the car into reverse while going 30 mph it slipped past neutral (i thought i was in 2nd and was gonna shift to 3rd but it slipped past neutral and i did a boo boo....tranny is totally fine though (seems like it anyways as it still shifts smooth and doesnt leak or make funny noises)


just read what aaron wrote...and that sounds proper....as long as thats what yours is doing...If your tranny doesnt shift unless u release the gas...then there is a problem

isnt the tranny shifting done with pressure and a diaphram? Maybe a hole in a diamphram?

or is that the clutch?

 

[Anonymous]

Yeah .. I have to take my foot off the gas pedal before it will go into gear. Like say im reving the car so i can have a fast take off or something, or like to peel out for say..so i put it in gear..but it just keeps revving, it like stays in neutral until i take my foot off the gas, then after the rmps go all the way down to idle, then it will go into gear

 

[Anonymous]

isnt there a vaccum hose to the tranny?

 

[amartin83]

It is supposed to do that THERE IS NO PROBLEM. Ford transmissions have a ratchet/dog mechanism to keep it from going in to gear when selecting drive or other gears from park while reving. If you just put into drive while idling it will take off just fine right? And does it shift from 1 to 2 and then 2 to 3 without having to lift off the gas? If it doesn't then there is a problem.

ratchet/dog mechanism ? wat does that mean.. is there a way to remove that or replace it or somethin'?

 

[amartin83]

Its kind of like the freewheel on the rear wheel of a bicycle, think about how that works. I'm sure there is a way to remove it but you will be pickin pieces of C4 transmission out of your teeth when you do your park to drive power shift one too many times. GM transmissions don't even last that long when you do that. It's not highly recommended. If you want to do a burnout that bad, get a 289.

well i playerd around with my C4 tranny a bit...i dont have the same problem, but i dont know if mine is stock either...it looked rebuilt and had a racing brand converter on it...

 

[Anonymous]

yeah, damn now i need to get a job. (but im not allowed to get one) ehhh, i think i should have it rebuilt.. i mean, i think its stock from 1967 .. so yeah, shouldn't be a bad thing to have it looked at

 

[Anonymous]

only problem with tranny rebuilds and stuff is that its so freakin expensive...i got extremely luckey and got mine for 120 bucks...i think a rebuild costs like 1200 bucks or something...would a shift kit help the problem that 1967FordMustangs is having? doesnt seem related really, but i dont know for sure.
