Question about 1993 GMC Suburban

Tranmission wont shift until engine redlines.

The tranmission on my 1993 Suburban wont shift when accelerating until the engine redlines. Seems to shift properly as far as engaging. Just wont go to the next gear til it redlines. What needs to be replaced to fix this?

I have a 2002 Celica GT 5-Speed and I shift at about 4k RPMs when getting on the highway and I still feel I'm accelerating to slow. Am i doing something wrong?


Not driving a corvette? Just kidding. More details are important. How slow is your acceleration? Is it 0-60 in 8 seconds, or 20 seconds? What is redline on your car? If redline is 5K then 4000 is a good responsible shift point. If redline is 8K then shifting at 4000 is probably robbing your engine of it's torque and horsepower band. I believe the GTS model has an 8K RPM redline, the GT may be lower, but in that case, shifting at 4K is too soon for strong acceleration. Your Tachometer should have redline clearly marked. For responsible use, stay below that, maybe 10-20%. For economy stay further still, but for power you need to let the engine use it's RPMS, especially smaller and fewer cylinder engines usually don't make their power until they are half way through the RPM range and above.

Automatic tranmission not working on overdrive, tacoma 2006


The knock sensor fault may be preventing the transmission from shifting to OD. The main engine computer also sends commands to the transmission computer. Your transmission valve body is controlled by electronics.

My a518 is holdin back when i accelerate but only in first is this fixable by a band adjustment or is it more serious than that


Band adjustment will affect shift quality but not timing.A throttle pressure adjustment may be needed to correct this problem.The cable coming from transmission is located on the passenger side and is pulled by the throttle linkage.there is a locking tap that will release the cable housing and allow it to slide back and fourth.You will need to move it towards the the front of engine to decrease throttle pressure and make shifts earlier.If this has no effect you have a throttle valve stuck in the valve body inside tranmission and this indicates that thereis damage since this tranmission is not prone to sticking valves.Good luck!

94 suburban not shifting or shifts hard


on top of the tranmission there will be wires that make the tranmission shift, check and see if they are loose or brokes, if that doesnt work try useing lucus for tranmissions, it is very effective
