Hi Guys! New here and first post. I'm in the market for a good used truck and I am thinking about taking a drive up north to check out a 1995 Sierra 2500 with a 6.5TD and a 3 spd automatic with an OD. The only thing I'm concerned about is the strength of the trannys in those trucks. I have a 1996 Sierra 2500 right now but it has a manual transmission.

I will be doing quite a bit of towing this summer. I have a 24' travel trailer and intend to tour the province of BC for the entire summer. That means lots of hills.

I know the 6.5 is not the strongest diesel out there but I like it and i'm familiar with it. I am just concerned about the automatic transmission and would like to know which transmission this truck "likely" has. The current owner doesn't know the model.

Also, are there any common issues I need to be aware of with gm automatics? I used to have a Firebird that burned up a couple of automatic transmissions so I'm a little leary of them now.

That being said, I also used to have an 2006 Sierra with the Duramax/6 spd Allison and it was awesome.

 

Thanks

It will have the 4L80E transmission. As far as Ive heard its a decent tranny and with only a small 24' lightweight trailer you shouldnt have a problem at all. WHat does your trailer weigh???

Hey thanks, GVWR on the sticker is 2858 kg. When we travel we're loaded to the max with a 100gal tank of veg oil in the box for fuel. I probably won't have that big of a tank in the new rig though but I'll likely be buying a 30 gal tank/tool box combo for the box and the truck has a matching canopy, oh and I have another 30gal tank that is going in now for dirty oil, along with a centrifuge/motor/pump and a vac pump. So ya, we'll be loaded down just as much. :cheers:

Youre gonna have somewhere near 7000Lbs of weight. Thats gonna be a lot of weight man, especially with a 6.5 at altitude. Ive gone through the mountains a lot, lving in Alberta, most of my summers are spent in BC. Ive never seen so many vehicles pulled over spewing steam/tranny fluid/oil as I did in the Okanagan Valley and the Coquihala hwy. You better get the cooling upgrade for the truck, a really big jesus tranny cooler and get that PMD relocation kit before you start hauling in BC during the summer. Also leaving as much weight as you can at home wouldnt be a bad idea, is the veg fluid that cheap??? I know nothing about bio diesel.

Oh ya, I know! :lol: I've spent my entire life in BC. Last Labour Day weekend we left PG fully loaded and fueled up and I rolled her across the gov't scale and scaled out at 12,000 lbs gross. We were headed for Osoyoos but we only had one really tough pull. Ashcroft to Logan Lake. It took a while and a lot of it was spent in 3rd gear at about 50kph but if that's what it takes, that's what you do. Like I said though, that was with a manual transmission. I'm not above hitting the hills early in the morning and/or travelling at night either. I'm a trucker, so I'm used to it.

And the veg oil isn't just cheap, it's free! :)

Most of the people that overheat are the idiots that go by you at 130Km/h with the A/C going. If youre a trucker, then ya, I should shut up, you know way more about this than I do. I cant wait to see what my new 6L will do through the mountains, first trip is gonna be to Radium :D Then maybe to Mara lake later on. Honestly though, Id do the cooling, PMD and tranny cooler upgrade.

Ya I see you have a 2006 2500HD. When I decided to experiment with the veg oil, I had one just like that. A crewcab, 4X4, with the 6.6 Duramax/6 spd Allison and I loved it. What an awesome truck and ya, pulling in the mountains is a breeze, you'll be laughing all the way up the hill and down the other side with that truck.

The last time the price of diesel went through the roof, I decided to buy this old project (paid $2000) and convert it over. I didn't want to tamper with the Dmax because it was still under warranty. After about 6 months of running veggie in this one, I sold the '06. I miss the truck but I sure don't miss the regular trips to the gas station.

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      Thanks for that, yes just because I could I measured what came out just to give me some guidance although I already knew to expect it to take at least 9.5 to just throwing in the whole 10 quarts off the shot and doing a one and done heat cycle to drop out the excess to get to the proper level. I don't recall exactly now what I measured that came out but was less than I put back in, I knew I spilled some on the garage floor but the main part was that I was thrilled in the discovery I did not have to touch my exhaust to flex it down. The gasket manipulating is a pain of course to create that clearance to take the pan out and put back in but its all very doable if one is careful and not forcing the gasket to flex too much. From the quote I got at a transmission shop of 900.00 here in Canada ( never asked at the dealer what they charge ) I saved 700.00 doing it myself after paying for the supplies so that to me paid very good wages !, and I knew what fluid was put in and that I had changed the filter and that the level is correct without any doubts.

      first oil change - 2026 2500HD gas

      By Chuck FB · Posted

      Typically its said and I agree so far that the engine oil drain plug oring is not required to be changed out unless you see some damage happening to the oring as apparently the oring lasts well. The dealer I have been getting a few parts from never even stocked the oring but instead stocked the whole drain plug that comes with a new oring which for the dealer is easier because they just throw in a new drain plug if there was any question about damage on it as well and charge the customer accordingly but again only if it is needed.    Also a hint about the drain plug oring to help it last vs a risk of causing damage to it, after its been removed and wiped off or washed off ( that is a whole other topic about some solvents damaging orings because some solvent types do ) to make sure to relube the oring with a bit of new oil so that it won't "grip" on the sealing surface of the pan and needlessly stress out the oring. Its no different than putting some oil on the sealing ring of the engine oil filter. So I just grabbed a new drain plug to have on hand although more recently bought just the oring as well but as its special it costs half the price of the drain plug ... !   Since you mentioned the hate to be empty handed theme, I am not sure what you have in the way of filter removal tools as I like using the exact sized for the filter steel 1" wide band with side to side swivel handle filter removal tool, and it can be used to snug up the filter without risk of damaging a filter as well ( its probably a lisle brand I have ). The drain plug hex size is 15mm and I always like using a 6 point socket if I have a choice and with this truck I've been using just a 3/8 ratchet that has a fairly long handle. Do you have a funnel that will work to pour oil in as that is definitely the short coming bastard part about the design with that fill port on the valve cover on such an angle that no normal funnel will even work. There are adapters and things on the market that will set into or screw into that fill port, I didn't want to deal with US shipping as that is all I was seeing at the time so caved and bought a Lisle brand multi vehicle fit adapter funnel kit and it really works well but there are much less expensive adapters out there that work in conjunction with an off the shelf funnel that would do the job also. Now that I have it, I like how it works and works so slick with the shape of the Amsoil 1 quart containers I have now switched over to. Whatever you do, have a funnel system of some sort as you will be swearing if you dropped the oil and then realize you have nothing to properly pour new oil in without spilling it all over the engine !.     Other comments, quite a bit of oil flows out down the filter when its cracked loose due to the housing above the filter so let it dribble down the filter until it slacks off flow and then remove the filter to create less possible mess. It seems these engines can sit for quite a while and drip and if you have time let it sit there and drip out of the engine as much as it wants. Also a good time to grease the 9 zerks on the front end, that's my typical practice anyway to grease the suspension and steering each time I change the oil. And remember to reset the oil change minder ( not something I am used to doing with older vehicles and equipment ).
