Urgent A4LD transmission rebuild advice is needed.

[wontgobackwrds]

Hello to all,

I am researching a transmission rebuild for my 1993 Aerostar V6 3.0L with A4LD transmission. I am in Europe, but have a relative in St. Louis who will be coming out to visit me on Aug. 15th. My cousin is willing to bring me a transmission rebuild kit if i can find one and get it to him prior to his departure.

HISTORY:
1st owner, 130,000 miles, changed ATF every 30,000 miles since new.

PROBLEM:
The transmisison still works(forward gears) , but unfortunately reverse no longer works. In PARK and REVERSE, when i give it gas the van slightly lurches forward, in NEUTRAL , OD, and D the van drives forward and seems to be shifting fine.

When i put it in reverse, the reverse lights light up so this leads me to believe that the shift linkage is ok. From the research i've done so far, it seems like the problem is probably a STUCK CLUTCH PACK.

One more thing that i thought i'd mention, prior to reverse giving out , the transmission would sometimes slip when starting from a stop on uneven roads(hills), otherwise , on level roads(in the city) there was no slippage from a stop. Anyone ever experience this problem?

Does anyone think that the 1st gear slippage and the stuck clutch pack are somehow related?

If so , could you please provide me with some info to solve the 1st gear slip and rebuild this transmission?

NOTE: my goal is to rebuild the transmission without investing too much money into it, since the van will probably see less than 1,000 miles per year(probably 300-600 a year, from now on) and will not be doing any towing, so it will basically be light usage.


REBUILD KIT:


I would really appreciate it if the guys who have already rebuilt the 4ALD/experts, please provide me with suggestions on what transmission rebuild kit to purchase.

thanks

Pete

Welcome to this forum! Check the low/reverse servo before you tear the transmission apart. It's possible that it might only need a new servo, servo O ring seals or servo cover gasket. Check the manual slide valve for wear in the area where the Z link connects, and the Z link to see if it's bent. They sell a manual index slide valve sleeve for this purpose. I would recommend the Transtec Viton D ring kit as a replacement for the O ring seals. Check WWW.TransmissionPartsUSA.Com.

thanks for your suggestions, they all require that i drop the trans oil pan, which at the moment i cannot do, the rebuild is scheduled for october-november.




i have done some research , and it seems like the problem is a stuck clutch pack. heres why:

when the van is in reverse or park, and i step on the gas pedal, the van moves forward about 3-4 inches. also, in park , the engine will not rev freely, it seems like it is under a load.

if my research is correct, because the forward clutch pack has welded its self together and will not/can not disengage, the van will only go forward.

on another forum i received a suggestion to make sure that the shift cable is properly adjusted . do you think an improperly adjusted shift cable can cause the aforementioned symptoms?



i guess i messed up with this thread, and all the details, sorry.

MAIN GOAL: i am trying to find a good rebuild kit that will most likely fix my no reverse problem, and i would like to order ASAP,, so that i can take advantage of the free shipping(cousin) otherwise , i will be looking at atleast an additional 75-$100 for shipping to europe.



thanks

Since low gear & reverse are controlled by the rear band & servo, it might be worth taking a look at.

 

[wontgobackwrds]

will first check out the reverse servo , when i finally decide to get my hands dirty.

til then , will be doing more research.


thanks
