MJ with some issues

[nameless]

looking for some help

 

88 4.0L

 

ax15 swap

 

 

 

when i start to go car gets to maybe 10 mph forward in either 1st or 2nd gear and locks up tires, rpms drop, then shoot up, then drop again

 

 

slams around pretty hard

 

 

but it drives normal and perfect in reverse... :wall:

 

can't figure it out looking for some input, thanks

you check your rear out yet

CPS wire melted to the exhaust? Torquing the motor forward makes it touch, but reverse tips it away (had the opposite problem with a 4 banger. Was the reverse light harness shorting out)
