There are you tube videos of Gen 2 cars accelerating, you can compare those to your car

The ATX trannys are not that strong from the factory, if you abuse them, they will fail sooner than they should. Just be prepared to shell out funds for a rebuild. If you treat them right and do all the maintenance, they will last over 300K (NoSlo has a 93 ATX and he is on his original transmission). My 94 ATX is on the second rebuild, first one at 85K and the second at 125K. Shosource at one time had a rebuilder that would beef up the ATX transmission, but I don't think the option is there anymore. You could contact them to see if they can still get the Road Ripper 1000

IT's a crapshoot. Go fast = $$. The design is barely enough to drive it like you want. If it was mine I would drive it easy off the line and push it after it gets a little speed. I had to do that with my GenIII and it made it to around 200k miles. When the tranny started to go I got rid of it. That engine was still strong af though. I do miss driving that thing

ive seen vids like this; hence my concern heres a vid of my sho going 0-50

notice in the video you attached they easily rev past 4k, mine shifts at 4k?? i don’t understand

 

[zoomlater]

I wonder if your secondaries are not working, search for IMRC to see how this sensor works. The butterfly's are open when the car is off, but they close when you start your car. There is a small lever in the middle of the butterfly's that you can pivot up to close the butterfly's, see if it moves after you start the engine

 

[luigisho]

It looks like there is a power issue. Is there a reason the car stops pulling near 4k? are the secondaries opening? THe car at wot should hold the shift longer, however if you let off the gas it will probably shift. If you are not lifting off the gas maybe the engine not performing correctly sort of does that for you. OR the transmission is not shifting correctly and you can't build up power from early shifting. Or the reve limiter in P and N is also about that RPM also. Very strange

1st guess check secondaries
2nd guess air/fuel/spark

maybe THATS what the burnt vaccuum line was, do u have a pic of what a properly hooked up secondary vaccuum loooks likee?

 

[luigisho]

What do you mean burnt? Is is not holding vacuum? Is it attached?

no it got burnt all the way thru im j not sure what it was for, ive sent you pictures before

how would i even fix it thinking the car is in park or nuetral? side note: car refuses to start in park, need to shift to neutral to turn it on

Intake Manifold Runner Control - !Help!

If you are getting vacuum through the solenoid when the engine is below 3950 rpms, chances are it is not bad. Trace the vacuum and see where it stops. There seems to be a lot of rust or oxidation on the butterfly shafts. Are you sure they are not stuck open (or closed)? Try putting a...

Did you try rocking the car to make sure the gear engages and stops the car? Sometimes vehicles don't register Park correctly.

sometimes it registers and engaged park but always need to shift into N to start even if it registers park

Sounds like a bad neutral safety switch

Also if that module is not operating correctly on the transmission tha could affect all manner of shifting. I would think there should be a tran s code somewhere though.

go get some new vacuum lines and see if it fixes the problem. your IMRC may still be good

You replaced with another piece of hose?

not yet idk where its supposed to connect

ok thank you, no trans code tho

Look at the picture in the IMRC link luigisho posted

If there is/are open vacuum leaks and the secondaries can't open, the car won't run correctly. The secondaries should have 1 location on each bank of intake butterflies. Should look like an oblong flying saucer with a hose barb coming out. Each bank has secondary butterfly valves to open the second set of runners. You need good vacuum and they can get sludgy and maybe need some cleaning/****. I never had issues with mine other than maybe a hose rotted and replaced.
