I decided to drain my transmission pan this weekend add some fresh pink anyhow i finally got the gall to do it this past weekend and after lots of reading up on this i figured i wouldnt strip the bolt oh yah and i wasnt too keen on heating it i read that if you put a bottle jack under the ratchet with some pressure you wouldnt strip it it worked like a charm just like the guy said so i just thought id tell all yall that it was hella easy and worked as if they hadnt locktited it thanks for your time

Yep, it works great, this is how I got mine off. Hardly any effort even. I'm convinced it isn't the loctite that makes it a huge pain, but the fact that the bolt they use is a cheap POS.

even if you get the plug out you are leaving all the sludge that is settled in the bottom of the pan, plus the plug is recessed and you are leaving about a qt of fluid in the pan as opposed to dropping the pan, also what about your filter change?

I bought a new bolt too. my old rounded head bolt is still installed. Would have taken the pan to a machine shop and had the bolt drilled out but none are open on weekends. i guess at 90,000 miles I'll buy a new pan and remove and reinstall the bolt before installation.

The new pans don't have drain plugs. Removed in 2004 as a cost save.

 

Once again you should drop the pan to service the filter anyway. Granted it is messier without a Drain Plug. But GM decided that they did not want mechanics to use the drain plug therefore the loctite. GM dealer mechanics are instructed not to use the drain plug.

It's MUCH easier to drain the pain via the drain bolt and then remove it for the filter change. I think that is what most people here are doing, makes the job a ton cleaner to drain first.

 

Good thing I'm not a GM dealer mechanic I guess, because I DO use the drain bolt.

Exactly. When you do it in a garage using a lift, it is no big deal to not use the drain plug. You just use one of those huge funel pans on top of your used oil collecting set up. Then you can catch all the ATF that splashes out.

 

However, when you do a transmission service in your drive way or in your garage at home with the vehicle maybe on jack stands, it is much cleaner and easier if you can drain as much fluid through a drain plug before you start to take the transmission pan off.

I agree it makes it less messy, but the trans drain plug has come and gone many times in GM vehicles over the past 40 years. But of all the trans drain plugs the one in the GMT800 is really useless. It is so far recessed in the pan that you can't drain that much anyway.

 

It really was useless and was worth GM saving $1.5 million per year. Just my opinion.

      OEM Trailer Hitch Receiver - Impact tightened by shop

      By Chuck FB · Posted

      Great info to have, I printed out what you had in your document as well as Newdudes post as I could see this mistake with the hardware happening very often if not realizing what type of special bolts are being used and just guess on bolt size for torque or the good enough "easy" method as per whack in the used bolts with an impact and send it !.

      Auto start stop disable

      By dennismc · Posted

      I installed the Auto stop eliminator on my 21 Sierra SLT shortly after I got it. They have a detailed video instruction on how, took me about 20-30 minutes to do. I was apprehensive too to start tearing apart a new truck but it was pretty easy install. Like you mentioned get some trim tools. I went to Harbor freight and picked up a set. If you can find some install videos/instructions to give you and idea for a plan of attack you should be fine.

      OCI, not when but why?

      By Chuck FB · Posted

      If all oil manufacturers had to meet a higher standard for not just the initial filtering of the oil but that they had to improve on their formulation so that the oil cleaned the engine such as the Valvoline R&P or the new Mobil product ( assuming it works similar of course ), and the oil was changed on an interval based on good UOA data, there shouldn't be any gremlins running around like miniture rats on top of your heads to be washed down into the oil pan below 😁

      OCI, not when but why?

      A while back on another thread there were comments and thoughts on air filters and I know that can tend to be a bit of a hot topic because of outfits that have a vested interest in selling aftermarket air boxes fitted with the gauze type of oiled elements touting the lower air restriction. However and unfortunately I don't know where I have seen the test results in the past about the amount of dirt through a test procedure that these style of filters do pass more dirt through than a properly designed ( not some cheap Chinese knock off ) paper/synesthetic media filter can do. Lake Speed had a conversation on that topic with one of the employees at Donaldson and there seemed to be a consensus of these oiled filters falling short in the absolute percentage of dirt holdback.    Which all ties back into how good the air filter is on the engine at keeping dirt out as that is going to reflect as a contaminant introduced into the oil as well as cylinder wear even if some of that dirt does find its way out of the exhaust rather then the crank case. Put another way that one can throw the kitchen sink at filtering the oil and using a bypass system which I fully expect will do nothing but good for the oils contamination but if the air filter system isn't doing its job then its preventing the engine from reaching the best wear/lasting case scenario instead.    Now perhaps this topic is or isn't for this particular thread but Grumpy Bear or anyone else for that matter, do you have access to some scientific trust worthy testing on engine air filter types to get some proper comparison data to post up.
