Transmission problems

[LittleBeast]

Feb 2007 - Isuzu place did transmission fluid flush, dropped the pan replaced the filter and filled with Royal Purple, same was done with all diff fluid etc.

March and April 2007 - VX starts having issues shifting from 1st to 2nd and 2nd to third sometimes staying in neutral for a while and not shifting, simply letting of the gas and waiting seems to help.

April 16 2007 - After reading a thread on here and seeing the same problem with someone whose mechanic forgot to run the trans through the gears when filling up I took the VX back to dealership to check Trans fluid level, they confirmed that there were no leaks however the trans fluid level was one quart low, so they went and got some royal purple and filled it back up.

Now - it is still having problems shifting every once and a while seeming to just get stuck in between gears normally between 1st and 2nd feeling like it is in neutral.

Questions - Does Royal Purple actually make an auto trans fluid that would be perfect for the VX? Could this be the problem? Could the trans being one quart low for almost two months have caused a permanent problem in which I will now have to get the trans rebuilt? Any other ideas? I have never ever ever had any issue with the trans before this I was just trying to make sure to keep the fluids in tip top shape and it cost me over $2k for all the work done in Feb (trans flush, gear fluid, brakes, etc) and now I am having problems with the things I was trying to extend the life of.

try disconnecting your battery for about a half hour if you havent, the transmission may just not be used to having the fluid full... i reset my computer that way the other day and without even realizing it i hit almost 5500.. my transmission before i reset the computer wouldnt let me go past about 4500 rpm before it shifted

The VX trans is weird. After I did my service (drop pan, refill, change filter, etc) I was slamming gears for a two days after from 2nd to 3rd. So I crawled under there again and pumped some more fluid (in my case, Mobile-1 Synthetic trans fluid) and after I got the level (seemingly) correct, the shifting is smooth and tidy.

In your case, if you are putting the VX in gear and it is not shifting from P to D or slipping into neutral, I can't imagine this is a good sign, but don't take my word for it.

I would have a trasmission shop check it out. Have you gone under your VX and checked the level yourself yet? Its messy and hot and a little scary to do it the way the manual tells you to, but....

Ryan,

Check the transmission's fluid level again. I had the same problem once. perhaps the guys at Isuzu don't know how to do it properly. Other than that, please follow gasmask's advice.

By the way, I use RP for the engine, but M1 for transmission...

Well if you ran it for 2 month's at 1 qt. low you probably damaged the trans. possibly.

Hi Littlebeast -

I'm not sure if this is related to your problem or not but read up on this thread:

This was for a tranny shifting problem I had a while back and what the fix was for it. Compare this problem to yours and see if the mechs can check this for you as well. It's a short descriptive post with problem and resolution included.

Hope this helps

Try changing your pcv valve.If it is sticking open it will suck oil from the valve cover. shawn
