won't engage into overdrive

accelerates good until about 40-45 mph then it doesn't let me accelerate anymore and sends rpms through the roof.

If i turn the overdrive off it will let me go faster than 40-45 but the rpms are really high.

I took it to autozone to had them give me codes for why the check engine light is on and came back with codes 1151 and 1152

I recently replaced the computer also.

If you have any idea what could possibly be wrong, that'd be great.

360ci

If you have a repair manual, I'd replace the sensors listed below or bring it to a shop:

P1151 - Lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Lean - Bank No. 2

P1152 - Lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Rich - Bank No. 2
