When my car did the exact same thing a few years ago and I researched this problem myself. After a lot of reading, I removed the overdrive clutch assy & replaced the "O" ring and put it back in & had my 4th & OD again. The Clutch assy was located at the tail end of the trans & I only had to remove the wheel on that side & trans, 1 plastic cover, and the end cover to gain access, 1 spring clip & it was out. I did have to use some creative C-clamp work to compress & release the clutches to get the seal in but persistance paid off.

Hope this helps. good luck

    Sorry, on my model the bell housing was at one end, next to the engine & the clutch pack I removed was at the other end up to the top of the trans., putting it near the inside of the wheel well. I don't expect that yours is the same, but I'm considering that it could be similar & hope that his helps. I would suggest you get the schematics for your trans & see if there's the possibility of the same based upon that. I reviewed several of my manuals but don't have your specific vehicle.



    Good Luck

How many times does a transmission supposed to shift starting from drive in a 1988 dodge ram with a 318 motor


Depends if you have a regular 3 speed automatic, or a 3 speed with overdrive.
Put it in drive, it will start out in first gear, then shift into second at about 15 MPH, into third at about 30-35 MPH. With overdrive, fourth gear will kick in at about 45-55MPH.

1973 chevy c10 pickup 350, truck is an automatic, starts up and goes into reverse and 1st fine but when i accelerate and the transmission shifts from 1st to 2nd the rpms keep increasing but the speed never...


Yeah Brother, those old square bodies are still neat. I have a '74 I put on a 4x4 chassis and 6.2 diesel w/overdrive automatic(700R4). Most likely you have a TH350 turbo trans and on the side front is a vacuum actuated can that operates the shift of the tranny. Any vacuum line connected to the carb or intake manifold will supply vacuum to it. It's originally a steel line with rubber connector tubes on the ends. Check the tranny fluid after warm up, in park, and be sure it has enough fluid in it. Luck Bro.

Transmission passing gear keep either getting stuck or it dont work because the motor keep idling up in first gear


this could be relative to many things, however you should check a few things before asessing the possibilities. When you put the truck in gear from park, Drive (overdrive) Should be the third notch you come to. so your in park, pull down clunk you're in reverse, clunk you're in neutral, clunk, now you are in drive. If you dont feel/ hear four notches/ clunks, you should be in overdrive. If you take off and it over revs 1st ( you shouldn't see more than 15 mph before it shifts on a stock transmission unless your flooring it and taking off fast) and then hard shifts to second gear, progresses to third gear normally, but wont progress into overdrive, it may be related to your vaccum advance, your shift linkage, or even possibly your timing. From the sounds of it, I would say vaccum advance is the likely cause, if it is otherwise in stock condition. If this is the case it could be as simple as reconnecting a vacum hose to the distributor. Should be to the left hand side of the cap, between the cap and intake manifold as you are looking at the firewall.

You have an overdrive relay issue. The tansmission is really a four-speed box, but the OD selector either locks our fourth gear or allows the car to shift normally into fourth. I use the OD on my volvo all the time, because the revs drop in half when the OD is activated, The relay is located behind the glove box, toward the center console. $10 buck on Ebay and your transmission should shift correctly again. I would try that BEFORE more expensive fixes, like OD solenoid $200 or transmission control module. Just for kicks a picked up a spare ECU on Ebay for $10 because these get costly if and when they go. Easy fix, though, a couple of plugs.
