Transmission Question .
« on: 17 Oct 2015 - 14:04:01 »
Hi;

     I am thinking of buying a vehicle that would serve as my Bug Out Vehicle. It is a State Surplus, 1995 Chevy 2500, 4 wheel drive, Automatic   that has a Utility Box on the back of it.

     124,000 miles on it      But    the Sale inspection report  states that the Transmission "slips".

     It is my understanding that a Mechanic could just drop the pan and tighten up the "bands" that make up the "shifting gears" in a automatic tranny.  Is this correct ?

     If the Tranny has to be rebuilt - what ballpark $$ 's will I expect to payout ?

     is there any other info I need to know before trying to buying this vehicle  ie:  production problems, unusual rust for that year,  etc.

Slipping is in most cases caused by worn clutch disc plates and require the removal an overhaul of the transmission. Depending on which transmission it has you're looking at $1200- $1500 or more including removal and installation.

You might be lucky and it is low on fluid or the fluid is burnt. A fluid change and some Lucas trans fix may get you going, but a overhaul is probably in the cards.

SV has a point but I think writer is my bet. If it was State owned I would "think" they were maintained and it is worn out. I could be wrong.  ::)  I would take cost of vehicle and see if your budget could handle a ...re-built ...tranny. Good luck.
I had a slipping tranny years back and it had to be re-built....just say.

Just as further info, I've rebuilt my share of automatic transmissions when I had my shop but that was prior to the overdrive crap, just the standard GM Turbo 350 and 400, Ford C4 and C6 and my favorites, the Mopar Torqueflite 727 and 904. Your bands handle the engagement of the clutch drums, but inside are alternating clutch discs and steel plates with an aluminum "pressure plate" that has seals on the inside and outside edges. Fluid pressure forces this against the clutch plates and steels, and you move in whichever direction is specified by which band is applied.  It's a bit more complex than that, but that's the gist. Slipping from worn clutches will overheat the steels and warp them so they're replaced as well as the clutches and all seals and bushings when an overhaul is done, alone with any electronic solenoids in the newer transmissions. The wife's Jeep CHerokee has a random shifting problem that I know is electronic, I've just put off dropping the pan and replacing all THREE electronic solenoids, and the fluid and filter of course. Most ignorant thing I've ever seen, having the computer control the shifting based off the throttle position sensor, through electronic solenoids inside the transmission. I plan on fixing it, selling it for $1200 and buying an old Jimmy or K5 Blazer for her.

I don't know about your transmission specifically but on some transmissions, such as a 46E dodge transmission, the band adjustment screws are mounted externally on the housing, above the pan.

As far as slipping goes, I have a story about a 1989 Honda Civic Wagovan with no reverse. To drive this little beast, I either had to park on a steep hill, in such a way that I could drive away forward or, stick my leg out of the door and "push" it backwards. It wasn't broken, it was just slipping. Sometimes, it would even kick in after I'd pushed it backward a few feet but, most times not. This went on for a few months before a friend told me to try TransX. I figured it couldn't hurt so, I gave it a shot. In less than 10 minutes after I poured this stuff into my transmission, I had reverse and it continued to work perfectly for almost a whole year before I had to add another bottle.

Keep in mind, this was LONG before I worked at the Honda Dealership and had access to transmission specialists. By that time, I'd already moved on to another car.

Don't talk about what you have done (or what you
are going to do). Do it and let it speak for itself.

Hi;

     Thanks guy's for all of the responses!  What you are saying is being told to me around here also.

     Today, I attended the sale and actually bought the truck.  $500. plus tags,tax and "commission fee's".  Came out to a total of $810. off the lot ! I never expected to really get it, there are people out there with more money than brains when they bid on some of the junk out there, But 1 old guy bid only 1 time against me and dropped out !

     Drove it to a local gas station to put some gas in it, then onto my local mechanic who is going to do a complete look over of all areas.  I am not a mechanic - but I did not feel any "slipping" in the gears, it seemed to go through the normal start to haul ass movement(s) that a vehicle can/will do. I drove it 24 miles to the garage for drop off. All seemed well with me. The tranny fluid look new and did not smell.

     the mechanic will also put it through his road test and I'll find out in (hopefully) 3 -4 days since has has other things to get done.

     The doors on the utility box are a little rusted/tight and some spray on grease should take care of that. There may/may not be a exhaust leak .

     If all is well from the mechanic, I will start to load up the utility box with all of the SHTF/Prep items I bought for it and maybe in a few weeks/months have that project out of the way.

     We are talking about a 4+ year quest ever since I found the old HPFF site and was prepping for 12-21-12.

     I have to start thinking about shelving in the compartments along with new locks for each compartment since keys were not provided from the sale, I only got 1 ignition key from the sale !

If the fluid appears and smells new then someone more than likely changed the fluid and filter in an attempt to fix whatever it might have been doing, and possibly tossed in a bottle of seal sweller of some sort. This stuff will soften the seals up so that they swell and work as they should...for a period of time. If this crap is used it will generally work fine for a while and then just totally shoot craps. Hopefully you got one that just needed a fluid and filter change and that's all they did. Still, you could part it out for more than that, the utility bed is worth that alone.

Hi;

     Well that may be what they did - time will tell.  I would have expected saw dust but did not see any indication !

For the cost, as long as the dipstick did not come out rusty, you got a good deal.

if your mechanic signs off on it great! if its going to be costly to repair sell it with disclosure about the slipping trans and make a profit!

Hi;

     well so far, I do not detect any slippage. Putting it in 4 wheel drive has to be watched closely - I think I have it in only to have to pull on the lever a little more ! Other than that - time will tell !
