I use tapatalk for viewing and it auto sizes so I can't tell. Piss poor programming on both tapatalk and vbulletin (that doesn't scale down large photos)

I know with Vbulletin if the image file is too large it will not allow you load an image file. You'll need to resize the image file before it will allow you to attach the file. Probably the tapatalk that is the problem.

Tapatalk auto resizes if you do one image at a time. Vb stupidly does not scale to fit it’s the combination caused the problem you witnessed

Here is an update :


I was able to add almost a quart more of transmission fluid when the temp was around 30c. I had similar delay issues right after that yesterday but when I started the car in the morning today, there was no delay on D or R in the beginning and it seemed to engage nicely until.. I did some shifting through gears for 10 minutes or so and eventually the delay was back.

So, should I try to add more fluid right around that time? Would something in the transmission system kick in and the delay would start after some fluid gets directed there? Does the transmission cooler immediately circulate the fluid or become active after the fluid heats up a little which may lower the fluid amount in the transmission?

Thoughts?

If you followed the procedure for filling the trans it tells you to go through all the gears and pausing at the gear. This will allow the ATF to flow through all the nooks and crannies in the trans. Sounds like you are still a little low.

Yes, I did that many times indeed before the fill. Now my car's transmission engages nicely when it is a cold start and then the delay and engagement issues eventually happen over time.

If the problems only come after warm up indicates ab viscosity related issue. Seal wear will lower pressure. Are your able to read realtime solinoid pressures you can compare to somebody else that doesn't have the issues

Not sure how I can read those.. INPA can show if they are activated and the amount of current on some but other than that I am not aware how to check the pressure on those..

Whatever reading: voltage, current etc to compare with other people

Are you manually shifting the trans or does it do this when you go from drive to reverse?

Here is what is happening right now (as it happened yesterday).

- I start the car, first thing in the morning and the transmission engages when I put on D immediately and I can drive around nicely for a while. Same thing happens when I manually put on gear 1.

- The engine (and transmission) warm up slowly and at one point (not fully warmed up), when I come to a stop for lights etc. , the slipping starts. I drive the car gently and manually switch up to 4 (and back to 1) to keep it going slowly. Most of the time this works as long as I keep going at a slow speed. Engagement would be back to normal.

- If I come to stop and go to P at a parking area etc. , when I put the car back on M1 or D, transmission may not engage until I manually shift up and down or sometimes if I go back to P and put back to D again.

- Once the transmission engages and warmed up, I can drive without problems both manually and in automatic.

I have followed the proper procedures I read on the internet but all this still makes me believe there is not enough fluid in there. I will try to add more fluid by raising the fill side up to see what happens next, I guess..

Thanks,
