lmao, If I recall it was like $6.25 for 25 6mm x 20mm , actually were bought by the Govt. for a job, and somehow landed on my workbench. IIRC the head diameter is same as OEM as well. I live and work in one of those geographic harmonic convergences ECS Tuning is 6 miles from where I work and McMast. huge distribution center 7 miles from where I live. HeavenMcMaster-Carr
That's where real men go shopping.
Yea I'm gonna just do fluid and filter change before I start delving into anything else that may not be the issue. I decided to try something this morning and don't know if it fixed the issue or not. I turned engine to on position and pressed on gas pedal for 20 secs to reset transmission code. I decided to run down to the gas station only 1 mile away. Funny thing is that I didn't go into limp mode and all gears shifted as it normally did. Still doing change. I bought this torque wrench for the pan and filter since both plugs I can pretty much do without a torque wrench.I would not worry about the Trans range sensor until after the ATF fluid and filter are changed out. Then make sure to clear the codes and see if anything comes back.
I eventually got tired of removing all of those small bolts by hand on the trans pans, so I started using an old adjustable electric drill. I set the torque to minimal when tightening and it really speeds up the job.
For re-filling, I bought a 2 gallon poly sprayer with a metal wand. I removed the spray tip and bent the end into a 90 degree bend, just wide enough to fit inside the fill tube. I used 7L just so I would not run out in the bottle. I do not wait for the trans to warm up, it warms very quickly and by the time you shift through the gears, it's already warm enough. Down here, it was often warm enough before starting as 95 is a nice cool summer day for us.
Are the places where you jack up the car 4 good points to use my 4 jack stand's with blocks of 2x4's to support car? I bought 4 2 ton stands.Be sure to clean the holes of the bolts if they have crud in them before removing them. A few seconds cleaning can save you the big hassle of removing a stripped bolt. And... they are T27, not T25, in case you didn't know.
Thanks for posting up the fix. ⭐Update:
I wanted to follow up with fix to my issue with limp mode. I had to critically think about what things occurred just prior to my initial problems. I had changed the oil and filter and thought about when I removed the filter I tipped it over slighting to remove it out of top of engine bay. When I did that some oil had poured out and onto the parts below in the engine bay.
The reason I had to circle back to this is because I had gotten code p0716 again on obdII, but without any issues with limp mode after my trans oil, filter and gasket change. This had happened a couple of times even after clearing codes. Thanks to cchief22 and some further talk offline about potential problems I decided to do the simple thing first. I jacked up car and looked at 16 pin harness and trans sensor harness located right below where I had assumed that the oil had spilled over. I was going to do ohm and continuity tests but decided to do the simple thing first as a process of elimination.
I had bought some CRC electrical cleaner and thoroughly saturated both plugs. When I did, tons of oil and dirt had fallen down. I wiped everything with some rags and did so again til most of dirt and oil was removed. I then unplugged both connections and saturated both sides completely again until stream was clear. I did inside the boot of 16 pin connection pin as I had noticed that this was off the harness casing and figured the oil spilled found its way into that area as well. Copious amount of oil and dirt had both fell down and did so again til spraying became clear. Dried everything again with rags until no residual dirt or oil was present. I reconnected the boot back to harness and used a zip tie to secure it on the harness perfectly. No more accidental boot coming undone there. Looking at harness plug and other side of connections, they were both pristine and bright connections once again. I reconnected plugs and lowered car. Took her for a spin and did so for the last few days without code coming on or issue with limp mode happening again.
Even though my car needed trans service done, I can with full confidence say that the oil spilled was the likely culprit as it seeped down into the disconnected boot and into the wiring harness and connection points. I will keep fingers cross, but I think this may have fixed the issue.
I wanted to follow up because I felt it necessary to show that it could be the littlest things that cause issues and you may have to just sit and think on what was happening just prior to this issue. I also wanted to give follow up info because many times I don't see people coming back and advising what was ultimate fix.
Thanks again for the community help, esp. cchief22, and hope that if you are having this issue to give you some hope of easy fix.
Now if it happens again I will be testing the ohms and continuity of wiring. Good luck all and Passat on!
