Angry 2003 Montero XLS transmission fix

I have a 2003 Montero with 106,000 original kms on the motor and transmission.I just changed the the transmission fluid to mitsu atf III as recommended buy the manual.The problem is that I can put it drive or reverse and it wont actually engage into drive or reverse,it's like it is in neutral.After about 1 minute or 2 of being in neutral it will finally drive when put in drive and go into reverse.My fluid level is correct at operating temp and I checked the level in neutral and it falls inbetween the marks for "hot" on the dipstick.I do not know which transmission fluid the previous owner had in it but the dipstick was reading overfilled,could this have caused some kind of permenant issue with the torque converter?.I also noticed that if I slam on the brakes while driving and come to a stop the transmission does the same as mentioned (no reverse or Drive) untill I put it in Neutral and then back into drive after a minute or so.This problem is definitely a pain in the ****

If anybody has had this problem on the 2003 transmission and know what the cause/fix is it would be great.

Sorry to hear about the issues you are experiencing. This might be very obvious, but are you checking fluid level with the engine running?

Thanks for your feedback!.I have checked the trans oil while in neutral and running and it there seems to be very little on the stick,however when I check the trans level when the engine is not running and cold the level seems to be well above the cold level.When I initially drained the old oil I measured the old fluid and replaced that exact amount with new fluid.I did not flush it only a drain so it measured about 5 liters.I didn't experience the problem before I drained the old trans fluid.

Thanks again!

That could be the issue. Make sure that trans oil level shows "FULL" when engine is running and vehicle is in Neutral, or in Park. This is when you need to measure level. Once engine is turned off, some fluid will drain back into transmission from the torque converter and from the oil cooler and it will show as as Overfilled.

Thank you good sir!.I added 1.2 litres while engine was running and cycled it through drive ,reverse and park and let it run for 10 minutes while I checked the level.It seems to be right up at the "hot" level while running and up to operating temp.I drove it later in the day and the problem seems to have been fixed.This transmission seems to be fickle even with the low Km's,but still shifts smooth for now.Thanks again

Keith
