96 FJ80 Transmission Shifting @ High RPM PLEASE HELP (1 Viewer)

[Rusty79]

I just did a head gasket on my '96 80 series and I am a bit stumped. I went through just about everything on the top end. New heater hoses (including PHH), milled the head, new seals all around, new injector o-rings, ARP stud kit, etc., etc.
Everything went together nicely. Engine is back up and running smooth.

Took it out for a test drive and now she won't shift right. First gear will wind up to 4,700 RPM before shifting to second. I have the same pattern for second and third gear. It doesn't matter if I shift through the gears manually or not the pattern is the same. I have adjusted the throttle valve cable. I can get the shifts to soften a bit but the shift points stay at the same rpm.

I have checked the trans fluid levels hot and cold so I know it's not a fluid level issue. I have done an exhaustive search here on Mud as well as Google without much luck.

Are there any 80 Series ninjas here on Mud that can lend some advice or additional trouble shooting?

I'm about to round up an old priest and a young priest to exercise the demons out of this thing

Bueller!?

Did your "power" button down by the gear selector get bumped? Maybe the indicator light is inop.

Check your "kick down" cable adjustment.

Power button is not the issue. I checked that as one of the first items. I have also checked and adjusted the throttle valve cable to infinity and beyond. I can soften the shift but the shift point never changes from shifting right near redline through 1st, 2nd, & 3rd.

The only thing that my collective posse has been able to come with is to move on to check the throttle position sensor.

I noticed on my Torque app, that the throttle number stays stuck at 94.

Thanks for the thoughts and feedback. I am open to anything else.

I have downloaded the '96 fsm. Any help on trouble shooting the TPS in conjunction with tranny would be greatly appreciated.

Yeah, I was gonna say, "TPS out of adjustment?".

Has this issue been resolved?

 

[xunogil]

does it feel like the tranny is slipping?
