| 2 1/2 tenths and MPH down? You may have a converter problem. I think line pressure may be part of problem with rocking but losing that much ET and MPH I would look at converter. https://postimg.cc/gallery/np3zpruo/"Dunning-Kruger Effect" -a type of Cognitive bias where people with little expertise or ability assume they have superior expertise or ability.

What type of gauge would be recommended for this, just any pressure gauge.
Low pressure will affect all aspects of the trans, converter, low, high, trans brake etc, the whole trans operates on Hyd pressure, knowing what pressure its operating at is invaluable information to have IMO Any 300psi Gauge will work, just make sure you can read it, in park, in low, in high and while you put it on the TB. while in low when you push the TB button the pressure will drop but SHOULD raise back up quickly. |

Aftermarket Case, BTE. Nothing in this transmission is stock. |

Reid pump in the dragster. FTI pump in the door car. The Reid pump was chosen years ago because I thought it was supposed to be the best. I don't know if that's true or not, but I've never had a pump-related issue. The FTI pump was chosen because I needed an input shaft and they offer a pump/input combo kit. I don't think there is nearly enough clarity when shopping for these things, as far as whether a given pump needs to be used with a ringed or ringless shaft.

In this car (I have 3) if I remember correctly it had an FTI Valve Body (Aluminum). The transbreak solenoid was changed last month ( 4 races on it) but it was changed to the exact same that was in it FTI Solenoid. |

| I still think you may be chasing two separate and different problems here. The rocking is probably due to low pump pressure and several here have gave some good ideas where and how to resolve that. Big red flag to me for possible second issue is 60 foot off 3 numbers and car 2, 1/2 tenths slow and that sounds to me like converter. Yes fluid pressure effects converter stall but I think it should be higher and original post did not say anything about motor blowing through converter. Now if the engine RPM was up over normal then I would think it is all in transmission. I would hate to see you pull transmission and fix low pump pressure and put it all back together with same converter and still be 2, 1/2 tenths slow. https://postimg.cc/gallery/np3zpruo/"Dunning-Kruger Effect" -a type of Cognitive bias where people with little expertise or ability assume they have superior expertise or ability. This overestimation occurs as a result of the fact that they do not have enough knowledge to know they don't have enough knowledge.

If the transmission has a bad seal/gasket and the fluid is just being directed right back into the pan then that would have an issue on 60ft and everything else downtrack, also at the hit. It would mean low and high are both slipping. Its hard for me to think this is a converter issue due to the statement that it was performing with no issues on the previous runs. Also while its not impossible, for there to have 2 issues simultaneously happen that are not related is the last thing I would consider. First thing to fix is the low pump pressure. |
