Test drove a 93 ATX that I might take as a partial trade on my motorcycle. At full throttle it will bounce off the rev limiter several times before shifting into 2nd gear. It doesn't slip but shifts late then seems normal. It also seems like cruise keeps trying to maintain speed but can't. Has anybody had this problem from a vss or tps sensor? Any ideas on this before I make a decision. Thanks in advance.

Could be a bad thing, you can run codes (check link in my sig) see if it comes up with anything tranny wise. 93s are the weakest year for the ATX also. Btw your sig pic is way too big, please resize to the forums limits.

Sorry about the size of the sig pic I didn't realise it was to big.

Sounds like a failing or fauly VSS. Have you followed Marcel's suggestion above and checked the codes yet?

I did not check the codes when I drove the car. I was on my way back home before I realized I should have pulled the codes. Spoke with a transmission shop yesterday and they said probably vss or possibly tps.

I don't know.... I would think if it was not getting a good vss signal it would shift early @ 3000 rpm or so. I am thinking more along the lines of the forward clutch piston starting to let pressure bleed off, making the car take that extra second for there to be enough pressure to force the shift.

What is the condition of the fluid. Is it at the proper level too?

The fluid doesn't look or smell burnt and is full.

While I was hoping for the 'simpler', electronic solution, I also agree that the forward clutch piston could be the one to blame. ;)

I guess I do not see the simple fix too often. That forward piston, and direct piston are junk before the upgrade to the harder steel. I remember years ago when we would see 4-5 taurii in every week with the 1-2 neutral slam shift. All associated with those types of repair. I guess that is still burned into my memory.

my updated steel piston is failing in the same way as well...

You have 184k and are on your 5th transmission. That is almost 37k per unit. Who do you have working on this thing....

Well if the guy comes up with the boot money I'm getting it in trade. Knocked $800 of the bike price for the car. What I'm ever going to do with SHO # 4 is beyond me but i have always wanted a black one with black interior so what the ****. Wish me luck.

Mr. Transmission needs some lessons on building transmissions it sounds like.

Mine only does it when warm. Cold; everything is nice, tight, and firm.

Try some fresh fluid. Add a bottle of Lucas Transmission oil stabilizer during the fluid change. It helps thicken up transmission oil.

I was actually going to try that this weekend, but opted to hit up the autoshow here in the T-dot. It is going to be freakishly cold anyways....

The fluid is only a few months old. I'll try the Lucas. Thanks.
