Code 700 and 740 r transmission and torque converter malfunctioning. Which most likely is caused by not enough fluid do to the leak. Code 401 is a egr (exhaust gas recirculation) valve problem. Most likely it's dirty. It depends on location of leak as to wether or not you can do it yourself. If leak is from pan you can get a filter and gasket kit. Remove all bolts surround pan and remove be careful as the residual fluid needs to be captured. Remove old filter replace with new filter. Use caution and scraping old gasket off pan. Check pan rim for any distortion or dings. Put new gasket on pan replace pan on vehicle using appropriate torque and sequences for tightening of bolts

Yes, but you need to have it in nuetral
SOURCE: Code PO740 and PO700 show
Best to have a transmission place work on this.
Here are the meaning of the codes:
P0700 Transmission Control System Malfunction
P0740 Torque Converter Clutch Circuit Malfunction
It maybe cheap to fix like a bad sensor. Or it maybe something serious going on. Best to have a transmission shop check it out.
Good luck.

P0700 is EATX code present.
It simply means that the engine computer has noticed that the transmission computer has a dtc in it. This causes the Pcm (engine computer) to turn the check engine light on. You will need to have the TCM (trans computer) checked for codes to know what to diagnose.
error code P1776 - Replace rear solenoid switch
Likely both related The P1776 probably kicked off the P0700 notification.
Hope that helps! Happy Motoring!
