Can someone help me understand what the following error codes mean?

P0174
P0748
P0758

I was driving down the road and all of a sudden the engine light and the transmission light came on. So I pulled oer and shut the car down for a few minutes. The car started and the lights were still on. I was able to drive it to my buddy's car dealership where he plugged it in and got the above error codes. We were able to reset the lights and the car drove as normal. However, I still got those codes and will need to take it to the Jaguar dealer.

How much will it cost me to fix?

 

Excerpted from the JTIS:

P0174 EMS
OBD II
Bank 2 combustion too lean

Air intake leak between MAF Sensor and throttle
Fuel filter / system restriction
Fuel injector restriction
Fuel pressure sensor failure (low fuel pressure)
Low fuel pump output
HO2 Sensor(s) (2/1, 2/2) harness wiring condition fault
Exhaust leak (before catalyst)
ECM receiving incorrect signal from one or more of the following components:
ECT Sensor, MAF Sensor, IAT Sensor,
IP Sensor, EFT Sensor, TP Sensor
---------------------------------------------
P0748 TRANS
OBD II
Line pressure control solenoid circuit malfunction

Transmission to TCM line pressure solenoid circuit: open circuit, short circuit
Transmission internal line pressure solenoid circuit: open circuit, short circuit
TCM Ground circuit:
open circuit, high resistance
Line pressure solenoid failure
---------------------------------------------
P0758 TRANS
OBD II
Shift solenoid B circuit malfunction

Transmission to TCM shift solenoid B circuit:
open circuit, short circuit to B+ V, short circuit to ground
Transmission internal shift solenoid B circuit:
open circuit, short circuit
TCM Ground circuit:
open circuit, high resistance
Shift solenoid B pressure solenoid failure

P0174 most likely indicates a vacuum leak on bank 2. The others codes indicate a borked tranny. How much will it cost at a Jaguar dealer? Well, how much you got?. Good luck.........
