SS Camaro starting in 3rd gear

Quick question...what would cause a 93 Camaro SS start off in 3rd gear...It's an automatic...when I put it in low and shift manually it drives and shifts fine. When it's left in D, from a standstill, it will barely go it at all. A buddy put some computer to it and it says it's starting off in 3rd gear... any help?

SS Camaro starting in third gear

Shift modulater, perhaps? On an older tranny, there is a vaccum line to control the shifts. This line may be blocked, or the modulater faulty. Just something to check.

93 was the last year of the 4L60 and it does not have a modulator. From my manual (yea, I cheated), the closest I can find is stuck governor valve or stripped governor gear. Might be worth a look. Its under the big domed cover towards the rear of the case. Tap off the cover, pull out governor and check the gear (plastic) and check for free travel on the valve inside.

Vacuum Modulator problem? not on this trans or car.

A computer should tell you nothing about what gear the trans is in. This statement confuses me.

You say the trans barely moves the car in "D" ? Shifter indicator is P R N D 3 2 1 ??

Could be a few problems. I need a bit more information on symptoms.

Does the trans drive OK in "3" shifter opsition? Or only shifts manual from 1 to 2 then 3 ??

If this is an LT-1 car, it should have a 4L60E trans.
If so, there are scanners that will tell youwhat is wrong. Sounds like there is no power to the trans. Default is 3rd gear in this trans. If thee are several codes for solenoid operation, check for trans power. Many possibilties,including a blown fuse.
Sounds like time to seek professional help...
