Hi,
I have a 1989 SN2001 with the 1.23:1 transmission. I want to replace the transmission oil, but just wanted to check that the dip stick I have is correct (see the attached photo). Does this dipstick look like the original? There is no MIN or MAX text on the stick, just a flattend area. Am I correct in assuming that the oil should reach the flat area (red lines on the photo)? I have read that the oil level should be checked by just allowing the dipstick to rest against the first o-ring in the transmission casing, and it should not be pushed in completely - is this right? Thanks, Greg

That is correct IF you check the level cold.
If you are checking the level warm, you must insert the dipstick fully and immediately after the engine is turned off. ------------- |

Thanks David 
So, to check the level when the engine/transmission is warm, can I take the dipstick out while the engine is running, then switch it off, quickly insert dipstick fully, and remove and check it? Also, After I replace the fluid, with the engine cold, can I used the "cold level method" to check that I have added enough oil? |

Greg,
I don't know if it is a problem or not, but it looks like you or missing the top o-ring on your disptick. I have a PCM 1.23:1 in my '95. I added fluid to mine recently and had to "study" the manual to understand what the heck they were trying to say. Poorly worded in my opinion, but it seems you are on track w/ David's help. |
